A rectangular field is twice as long as it is wide. If the perimeter is 240 meters, what are the dimensions?
Answer
40 m by 80 m meters
How to solve it
1
Let width = w, length = 2w
2
Perimeter: 2w + 2(2w) = 240
3
6w = 240
4
w = 40 m, length = 80 m
Hints
Set up variable for width
Length is twice width
Use perimeter formula
Solve for width
