Question 369094: the length of a rectangle is 3 inches more than twice the width. the perimeter is 36 inches. what is length and width

Let l be the length, w be the width, and P be the perimeter.
l=2*w+3 given
P=2*l+2*w formula for perimeter of a rectangle
P=2*(2*w+3)+2*w
36=2*(2*w+3)+2*w
36=4w+6+2w
36=6w+6
30=6w
w=5
l=2*w+3
l=2*5+3
l=13
Thus, the length is 13 and the width is 5.
Therefore the perimeter would be 13*2+5*2 which would equal 36!
I hope this helps!
