Answer 2

Given,

Dimensions of triangular field = 55m,60m,65m

Rate of laying grass = Rs. 8 per m²

To find,

Area of field and cost of laying grass.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Semi perimeter of field = (55+60+65)/2 = 90m

Area of field = √90×(90-55)×(90-60)×(90-65) = √(90×35×30×25) = √2362500 = 1537.04 m²

Cost for 1m² = Rs. 8

Cost for 1537.04 m² = 8×1537.04 = Rs. 12296.32

Hence, area of field is 1537.04 m² and Cost for laying grass Rs. 12296.32
