Problema Solution
the width of a rectangle is 6 yards more than twice its length. the perimeter is 30 yards. what is the length
Answer provided by our tutors
Let
w = represents the width, w>=0
l = represent the length, l>=0
The width of a rectangle is 6 yards more than twice its length:
w = 6 + 2l
The perimeter is 30 yards:
2(l + w) = 30
We have the following system of equations:
w = 6 + 2l
2(l + w) = 30
........
.........
l = 3 yd
w = 12 yd
The length is 3 yards.
