Question

The perimeter of some traffic sign must be 120 inches. Also, its length is 8 inches longer than its width. Find the dimensions of this sign???? Help?

Answer 1

width be x
lenght =8 inches longer than its width= x+8
perimeter is 120=2*(width+length)
2*(x+x+8)=120
(2x+8)=60
2x+8=60
2x=60-8
2x=52
x=26 inches
widht=26inches
length=width+8=26+8=34 inches
