Question 246187
The perimeter of a rectangle is 210ft. The length is 15ft. less than twice the width. What is the length and the width? 
-------------------------
Let the width be "w".
Length = "2w-15".
--------
Perimeter = 2(length + width)
210 = 2(2w-15+w)
105 = 3w-15
3w = 120
w = 40 ft (width)
---
length = 2w-15 = 80-15 = 65 ft (length)
