Question

The base of a triangle field is 5 times it's height. If the cost of cultivating the field is rs 3000 at the rate of rs 1 per meter square .Then find the height and base of the field

Answer 1

Answer:

let the height of the triangle be x

then,the base of triangle is 5x

given,

The cost of the cultivating of the field rs 3000,if the rate of cultivating of the field rs1/m2.

The area of the triangle=rs3000÷rs1/m2

                                       =3000m2

A/Q

the area of the triangle=1/2×base×height

                => 3000m2 = 1/2×(5X)×(X)  

                =>3000m2 = 1/2 ×(5X2)

               =>3000m2×2 = 5X2

               =>6000m2 = 5X2

               =>X2 = 6000m2÷5

               =>X2 = 1200m2

               =>X = √1200m2

                   X = 34.61 m

find base and height.
