Question

A playground is rectangular in shape. If its length is 60 m and breadth is 50 m, find the cost of fencing it at the rate of ₹ 2.50/metre.

• A. ₹ 550
• B. ₹ 540
• C. ₹ 650
• D. ₹ 660

Answer 1

The correct option is A

₹ 550

Given: The playground is rectangular in shape.
Perimeter of the rectangle = 2( length + breadth )
= 2( 60 m + 50 m )
= 2( 110 m ) = 220 m
Cost of fencing 1 square metre of the playground = ₹ 2.50
Cost of fencing the playground = Cost of fencing 1 m of the playground $\times$ Perimeter of the rectangle
$\Rightarrow$ Cost of fencing = ₹ 2.50/m $\times$ 220 m = ₹ 550
Therefore, cost of fencing the playground will be ₹ 550
