By the Pythagorean Theorem, the diagonal is the hypotenuse of the right triangle formed by the diagonal and the two included sides.

c2 = a2 + b2 so the diagonal is the square root of the sum of the squares of the rectangle's length and width.

Example : for a rectangle 4 x 3, the diagonal is sqrt(32 + 42) = sqrt (25) = 5

A rectangle is 4 ft by 6ft What is the length of the diagonal of the rectangle?

To find the length of the diagonal of a rectangle, you can use the Pythagorean theorem. In this case, the diagonal forms the hypotenuse of a right triangle with the sides being the length and width of the rectangle. So, the diagonal (d) can be calculated as d = √(4^2 + 6^2) = √(16 + 36) = √52 ≈ 7.21 feet.
