Question 1122651: the perimeter of a rectangular pool is 360 yd. if the length is 20 yd less than four times the wdth, find the length and the width. there is a picture of a rectangle wth the width marked as 'w" and the length marked as "4w-20" For the Perimeter don't forget it's P=2L+2W Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! W=x
L=4x-20
L+W=5x-20
Note: L+W = half perimeter, or 180, since that is half of 360
5x-20=180
5x=200
x=40 yd width
4w-20=140 yd length
