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
