Find area of rectangle when given perimeter and diagonal I was helping my niece (going into 10th) with summer math, and am stumped. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. C++ Examples. So this rectangle is divided into 2 right angled triangles(90 degrees each). This article has been viewed 464,105 times. You can use Pythagoras' theorem to find the diagonal from the length and width of the rectangle: d^2 = … Then s² = 196, and s = 14 m. The area is 48 x 14 = 672 square meters. Adjacent sides of a rectangle is unequal and opposite sides are parallel to each other. If you have the length and a diagonal, you will first have to figure out the width, using the formula of Pythagoras. In this rectangle one of the sides is the height, which coincides with the length of the edge. Answer to: Find the area and the perimeter of the rectangle with diagonal 2 10 in and the width 2 2 in.

\n<\/p><\/div>"}, How to Find the Area of a Rectangle Using the Diagonal. The perimeter, or twice the length plus twice the width, is 33, so 2(2w) + 2w = 33. Find the width of the rectangle and use the animation or the calculator above to verify your answer. How do I find the length and width? Every day at wikiHow, we work hard to give you access to instructions and information that will help you live a better life, whether it's keeping you safer, healthier, or improving your well-being. We use cookies to make wikiHow great. How do I find the area of a rectangle if width and perimeter are given? To find the diagonal of a rectangle formula, you can divide a rectangle into two congruent right triangles, i.e., triangles with one angle of 90°.Each triangle will have sides of length l and w and a hypotenuse of length d.You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: So w² + (w² + 4w + 4) = 2w² + 4w + 4 = 20. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/0\/02\/Find-the-Width-of-a-Rectangle-Step-1.jpg\/v4-460px-Find-the-Width-of-a-Rectangle-Step-1.jpg","bigUrl":"\/images\/thumb\/0\/02\/Find-the-Width-of-a-Rectangle-Step-1.jpg\/aid5034810-v4-728px-Find-the-Width-of-a-Rectangle-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"
