Question

The diagonal of a rectangle is 25 inch. the width is 15 in. what is the area of the rectangle?

Answer 1

D= diagonal= 25 in
w= 15 in

A= w√(d^2﹣w^2)

A= (15)√(25^2 - 15^2)
square in parentheses

A= (15)√(625 - 225)
subtract in parentheses

A= (15)√(400)
take square root of 400

A= (15)(20)

A= 300 in^2


ANSWER: The area is 300 inches squared

Hope this helps! :)
