If the rate is at Rs7 per meter square, the cost of laying grass in a triangular field will be Rs150150
<h3>Surface area of triangular field</h3>
The formula for calculating the surface area of a triangular field is expressed as;
Surface area = 2(lw+lh+wh)
Substitute the given dimension
Surface area = 2(50(65)+50(65) + 65(65))
Surface area = 2(3250+3250+4225)
Surface area = 2(10725)
Surface area = 21450 square meters
If the rate is at Rs7 per meter square, the cost of laying grass in a triangular field will be Rs150150
