we know total cost is 52200
the rate of cultivating is 14.50 per 100 m
this implies its area will be 360000
and its base is twice its altitude
so if altitude is x then base will be 2x
by formula of 1/2 × b × h we have area as 1/2× x × 2x = x^2
we know area is 360000
so x^2 will be equal to 360000 this implies x is equal to 600 and 2x as 1200
so b is 1200 and h or a is 600
