Question

The side of a triangular field is 52m, 56m and 60m find the cost of levelling the field Rs 18 per meter, if a space of 4cm is to be left for entry gate?

Answer 1

Given:

The side of a triangular field is 52m, 56m, and 60m

The cost of leveling is Rs. 18/m.

To find:

The total cost of leveling.

Solution:

1) Leveling is done at the boundary of the field so we will find the perimeter of the field first

The perimeter of the field:

• 52+56+60

• 168m.

The length which needs to be leveled is 168-4 = 164 m (space of 4m is left for the entry gate)

2) Cost of leveling is 164×18

• Rs. 2952

The total cost of leveling is Rs. 2952

Answer 2

Answer the cost of leveling equal RS 2925
