Question 38519: i need this answer right away thank you!
the perimeter of a rectangle is 56 inches. the length is 5 less than the width find the demensions.
Answer by Nate(3500) About Me  (Show Source):
You can put this solution on YOUR website!
Perimeter = 2l + 2w
Where the length = (w-5)
Where the width = (w)
56 = 2(w-5) + 2(w)
56 = 2w - 10 + 2w
66 = 4w
16.5 = w
11.5 = l
Doesn't the length's measure generally is greater than the width?
