Question

Rob is fencing a rectangular park with barbed wires. The park is 200 feet long and 150 feet wide. The cost of fencing the park is $\$$25 per foot.
Find the cost of fencing the park.

• A. $\$$20500
• B. $\$$27500
• C. $\$$14500
• D. $\$$17500

Answer 1

The correct option is D $\$$17500

Length of the rectangular park = 200 feet
Width of the rectangular park = 150 feet

To find the cost of fencing, we require the perimeter of rectangular park.

Perimeter of rectangular park = $2\times (length+breadth)$
i.e., $2\times (200+150)$ feet
= $2\times 350$ feet
= 700 feet

Cost of fencing 1 foot of the park = $\$$25
Cost of fencing = Perimeter $\times$ Cost of fence per foot
= 700 $\times$ 25
= $\$$17500

Thus, the cost of fencing the rectangular park is $\$$17500.
