Question

The length of a rectangular frame 15 inches,and the width of the frame is 8 inches.What is the length of a diagonal of this frame in inches

Answer 1

17 inches

Explanation:

Applying the Pythagorean theorem, the diagonal becomes the hypotenuse

Let d represent the diagonal

d^2 = 15^2 + 8^2

d^2 = 225 + 64

d^2 = 289

Take the square root of both sides

d = 17 inches
