Question

Traffic signs are regulated by the Manual on Uniform Traffic Control Devices (MUTCD. The perimeter of a rectangular traffic sign is 130 inches. Also, its length is 9 inches width. Find the dimensions of this sign.

Answer 1

Answer: 56 x 9 inches

Perimeter minus the two known sides will give us the length of the other two sides

130 - 9 - 9 = 112

Divide that by 2 to get the length of one side

112 / 2 = 56

The sign is 56 by 9 inches
