Answer:
Rs 10500
Step-by-step explanation:
Sides of the triangle are a=50m,b=65m,c=65m
Area of triangle, by Heron's formula =
s(s−a)(s−b)(s−c)
where,
s=
2
a+b+c
s=
2
50+65+65
s=90
Area of triangle =
90(40)(25)(25)
Area of triangle = 1500m

Cost of laying grass = Area ×7
Cost of laying grass =1500×7
Cost of laying grass = Rs 10500
