ready with the my que

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=2a+b+c

s=250+65+65

s=90

Area of triangle = 90(40)(25)(25)

Area of triangle = 1500m2

Cost of laying grass = Area ×7

Cost of laying grass =1500×7

Cost of laying grass = Rs 10500
