What does it mean to find the diagonal of a rectangle? When you want to find out the diagonal of a rectangle, it can be a complicated process to do so by hand. The formula is: A = L x W. where A is the area, L is the length, W is the width, and X means multiply https://www.youtube.com/watch?v=T5D_tT2tjTw&feature=youtu.be&t=47, https://www.youtube.com/watch?v=T5D_tT2tjTw&feature=youtu.be&t=150, https://www.mathsisfun.com/pythagorean_triples.html, https://www.youtube.com/watch?v=3ttvpmlhmrI&feature=youtu.be&t=64, https://www.youtube.com/watch?v=3ttvpmlhmrI&feature=youtu.be&t=106, https://www.mathopenref.com/rectanglediagonals.html, https://www.omnicalculator.com/math/diagonal-of-rectangle, consider supporting our work with a contribution to wikiHow. But, it is given that area of the rectangle has to be greater than 18 sq. The diagonal of rectangle is 25, its area is 168, find width and length. We know that, Area of rectangle (A) = width√ diagonal 2-width 2. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. EDIT: From the comments and solutions this is not possible. Generally, finding the diagonal of a rectangle means to find the length of the rectangle diagonal. Divide by 2: w² + 2w + 2 = 10. As long as you know the area or perimeter, as well as the length of one side of the rectangle (or the relationship between the length and width), you can find a missing dimension. K-12 students may refer the below formulas of rectangle to know what are all the input parameters are being used to find the area, perimeter, diagonal, length or side of a rectangle. (Jump to Area of a Rectangle or Perimeter of a Rectangle) A rectangle is a four-sided flat shape where every angle is a right angle (90°). Dividing by √5: x = 40 / √5 = 40 / 2.236 = 17.9 cm. In Part B, find the missing side using the area and the side provided and then find the diagonal using the theorem. In that case, you would use the formula: perimeter = 2 × length plus 2 × width.
