Question

the length of a garden is 200 metre and breadth is 150 M find the cost of fencing @ rupees 150 per metre square​

Answer 1

Length = 200m

Breadth = 150m

Perimeter ( Fence ) = 2 × ( Length × Breadth ) = 2 × ( 200 + 150 ) =700 m

cost = 150 × 700 = 21000

Answer 2

Cost of fencing= Perimeter of garden* cost of fencing per meter

Cost of fencing= 2(l+b)* rs 150

Cost of fencing= 2(200+150)* 150

Cost of fencing= 2(350)* 150

Cost of fencing= 700* 150

Cost of fencing= rs 105000
