Question

The diagonal of a rectagle is 25 in the width is 15 what is the length​

Answer 1

Answer:

20 in

Step-by-step explanation:

Remark

This is a Pythagorean Theorem question.

Givens

a = 15 in

b = ??

c = 25 in

Formula

a^2 + b^2 = c^2

Solution

15^2 + b^2 = 25^2

225 + b^2 = 625                 Subtract 225 from both sides

225-225+b^2 = 625-225   Combine

b^2 = 400                            Take the square root of both sides

sqrt(b^2) = sqrt(400)

b = 20

The length is 20 in
