Answer:
Height = 300m
Base = 900m
Step-by-step explanation:
Cost per 100m^2 = Rs.36.72
Cost per 1m^2 = (36.72)/(100) = Rs.0.3672
Area = Total Cost/Cost per m^2 = (49572)/(0.3672) = (49572*10000)/(3672) = 1,35,000
Height = x ; Base = 3x.
Area = 1/2*base * height
1/2 * 3x * x = 135000
x^2 = (135000 * 2)/3
x^2 = 45000 * 2
x =
x = 300
Height = 300m
Base = 900m
