Question

The length of a rectangle is stored in a double variable named length, the width in one named width. write an expression whose value is the length of the diagonal of the rectangle java

Answer 1

by definition, a rectangle contains 90° angles so you can use the Pythagorean Theorem to find the length of the diagonal.

Diagonal(D)² = Length (L)² + width (w)²

D = $\sqrt{L^{2}+ w^{2} }$
