base of the triangle is equal to 18 m=a
equal sides of triangle are equal to 15 metre each =c=b
area of triangle is equal to
√[s (s -a)( s -b)(s -c )]
s=(a+b+c)/2
s=(18+15+15)/2
s=48/2=24
AREA=√[24(24-18)(24-15)(24-15)}
=√(24*6*9*9)
=√11664
=108m^2
rate of cost of levelling it = RS.15 per square meter
the cost of levelling it =15*108= RS. 1620
