Question

The base of a trianglar field is three times its altitude . If the cost of levelling the field at 30.50per sq metre is 7350 find its base and height .

Answer 1

Step-by-step explanation:

We know the area of a triangle = x (base) x (altitude)

Let the altitude of the triangle = a

therefore, base length = 3a

=> area, A = x 3a x a

=> sq.metre

Price of levelling the field of area A = A x 30.50

Given : 30.50 A = 7350

            => A = 240.98 sq.metre

Therefore,

                  =>  a = 12.67 metre

Hence, altitude length = 12.67 metre , and base length = 38.01 metre
