Question

The length of a rectangle is 3 inches more than its width. The area of
the rectangle is 40 square inches. What is the length, in inches, of the
rectangle?
(1) 5 (3) 8.5
(2) 8 (4) 11.5

Answer 1

A=LxW
A=(w+3)*w
40=(w+3)*w
40=w^2+3w
w^2+3w-40=0
w=5

The width of the rectangle is equal to 5, the length (because the length is w+3) is equal to 8.

Answer 2

2 is the answer

Answer 3

I get the same answer as chaise: length = 8 inches
