# Field X and Y are to be enclosed with a fencing at the cost of Rs.40 per meter. If the cost on field X is denoted by Cx and that on field Y is denoted by Cy, we haveCx=Cy,Cx<Cy,Cx>Cy,cannot be determined

A
Cx>Cy,
B
cannot be determined
C
Cx<Cy,
D
Cx=Cy,
Solution
Verified by Toppr

#### The correct option is ACx=Cy,Perimeter of field X=470+290+(470−180)+180+(470−290)+470=4×470=1880m.Perimeter of field Y =4×470=1880m.Hence, Cx=1880×40 and Cy=1880×40⇒Cx=Cy
