Question 664183: The length of a rectangle is 5 cm more than the width. The perimeter is 38 cm. Find the length and width
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
l = w+5
p = 38 = 2w+2l
Substitute length into perimeter
...
2w+2(w+5)=38
Distribute the 2
2w + 2w + 10 = 38
4w + 10 = 38
4w = 38-10
4w = 28
w = 7 cm
l=7+5=12 cm
...
check
2(7) + 2(12) = 14 + 24 = 38
