Step-by-step explanation:
Diagonal of a rectangle divides it into two right triangles, BCD and DAB. The diagonal of the rectangle is the hypotenuse of these triangles. We can use Pythagoras' Theorem to find the length of the diagonal if we know the width and height of the rectangle.
As a formula:
Diagonal = √ w 2 + h 2
where:
w -is the width of the rectangle
h -is the height of the rectangle
