A rectangular field is twice as long as it is wide. If the perimeter is 360 what are the dimensions?
We are given or know the following about the rectangle
Since l = 2w, we have 2l + (l) = 360
3l = 360
Divide by 3, we get l = 120
Which means w = 120/2
w = 60
We are given or know the following about the rectangle
- l = 2w
- P = 2l + 2w
- Since P = 360, we have 2l + 2w = 360
Since l = 2w, we have 2l + (l) = 360
3l = 360
Divide by 3, we get l = 120
Which means w = 120/2
w = 60
