QuestionHow can I find the side of a rectangle if perimeter is given?DonaganTop AnswererYou can't. With any given perimeter, an infinite number of lengthwidth combinations would be possible.

QuestionHow do I find the perimeter with difficult shapes?Community AnswerIt can help to break difficult shapes up into simpler shapes. Use area formulas for these simpler shapes to help you find all the side lengths of the complex shape.

QuestionCan I figure out the perimeter of an odd shape if I know its area?DonaganTop AnswererNo, the "oddness" of the shape makes it impossible to know the perimeter without more information.

QuestionThe perimeter of a rectangle is 40cm & its breadth is 4cm less than the length. How do I find the length & breadth of this rectangle?DonaganTop AnswererLet L be the length. Then (L  4) is the breadth. The perimeter is twice the length plus twice the breadth: 2 (L) + 2 (L  4) = 40. Solve for L. The breadth will be 4 less than L.

QuestionHow to find an expression for the perimeter of a rectangle with a given area (trinomial 6x^2+17x+12 format)?Community AnswerTo find the perimeter of a rectangle with a trinomial equation as the area, you'll need to factor this equation to get the sides. Once you've factored the equation, you can then add the sides to find the perimeter.

QuestionA rectangle has a ratio of 3:2. The area is 294 square meters. What is the perimeter?OrangejewsCommunity AnswerA = 294 m^2 = 3x*2x = 6x^2 for some x So x = 7m Perimeter= 2(3x + 2x), so plugging in the now known value x=7m yields P = 70m

QuestionHow do I find the perimeter of a rectangle if I have the area, x squared  81, and that's it?DonaganTop AnswererIf you assume that the length and width are both 9, you could easily find the perimeter. However, you can't really assume the length and width are each 9, so you don't actually have enough information to calculate the perimeter.

QuestionCan I find the perimeter if I don't know the length of the sides?DonaganTop AnswererNo, if you don't know any of the sides, you can't find the perimeter.

QuestionWhat is the perimeter of a rectangle that has one of the sides 7 m in length and the area is 651 m squared?DonaganTop AnswererDivide the area by the length. That gives you the width. Find the perimeter by adding twice the length to twice the width.

QuestionHow do I find the total square area if one rectangle is 32 sq area and one is 48 sq area?DonaganTop AnswererAdd 32 and 48.

QuestionIf width = x and length = x + 40% and perimeter of the rectangle is 360 m, how do I find the value of x?DonaganTop AnswererThe width is x, and the length is (x + 40%). (x + 40%) = (x + 0.4x) = 1.4x. The perimeter is twice the width plus twice the length, which is (2x) + 2(1.4x) = (2x) + (2.8x) = 4.8x.

QuestionWhat if the width is 840 m and the length is 48 m longer?DonaganTop AnswererLet w be the width. Then the length is (w + 48). The perimeter is twice the width plus twice the length, or 2w + 2(w+48) = 2w + (2w + 96) = 4w + 96 = 840. Then 4w = 744, and w = 186 m.

QuestionHow can I find the perimeter of rectangle, if the width and diagonal is given?DonaganTop AnswererUse the Pythagorean theorem to find the length. (Square the diagonal, and from that subtract the square of the width. That gives you the square of the length, so find its square root.) Once you know the length, double it, and add twice the width. That's the perimeter.

QuestionHow do I find the perimeter of rectangle when area and length is given, but breadth is not given?DonaganTop AnswererDivide the area by the length. That gives you the breadth (width). Add twice the breadth to twice the length to get the perimeter.

QuestionHow do I find the border of a square if I know its area?DonaganTop AnswererIf you're asking about the perimeter of a square, first find the square root of its area. That gives you the length of any side. Multiply that length by 4 to get the perimeter.

QuestionHow do I find the perimeter of a rectangle if I am only provided the area?DonaganTop AnswererIt can't be done, because a rectangle with a given area could have several different length/width combinations (leading to different perimeters).

QuestionHow do I find the perimeter if length is 40 cm and width is 5 cm? What is the height?DonaganTop AnswererThe "height" of a rectangle is also referred to as it width. As shown above, a rectangle's perimeter is twice its length plus twice its width.
