Question 358353
Dave and jane wells have a new rectangular driveway. The perimeter of the driveway is 168 feet. the length is 12 feet longer than three times the width. what are the dimensions of the driveway?
...
let width be x
length = 3x+12
...
perimeter = 2(L+W)
2(x+3x+12)=168
2(4x+12)=168
8x+24=168
8x=168-24
8x=144
/8
x=18 m the width
length = 3x+12= 3*18+12
=54+12
=66 m
66m by 18 m
