Question

The length of a rectangle is 3 inches more than twice its width, and its area is 65 square inches. What is the width?

2.5 in.
5 in.
6.5 in.

Answer 1

You would do
(l=length W=width)
2.5*2+3=8L*2.5W= 20 So 2.5 width is No

5*2+3=13L*5W=65 So width of 5 is correct so 5 in width is correct

6.5*2+3=19.5L*6.5W=84.5 to high so No


The correct answer is 5 in wide

Answer 2

formula of a rectangle: A=1(w)
the length would be 2w+5 answer 5
