Question

A rectangle is drawn so the width is 3 inches longer than the height. If the rectangle's diagonal measurement is 39 inches, find the height.

Answer 1

about 26.04 inches high

29.04 inches wide

39^2 = about 26.04^2 + 29.04^2

use the pythagorean theorem

d^2 = w^2 + h^2

d^2 = (h+3)^2 + h^2

2h^2 +6h =39^2 - 9

complete the square or use the quadratic formula
