How to find diagonals of a rectangle?
The formula for the diagonal of a rectangle is derived using the Pythagoras theorem. The length of the diagonal of the Rectangle is found using the formula shown below. Let us consider a rectangle of length "l" and width "w". Let the length of each diagonal be "d". Applying Pythagoras theorem to the triangle ABD, d 2 = l 2 + w 2. Taking square root on both sides, √ (d 2) = √ ( l 2 + w 2 ). Thus, the diagonal of a rectangle formula is: √ (l² + w²) and thus the diagonals of a rectangle can be calculated when the length and width of the rectangle are known.
