Question

the area of a triangle is equal to that of a square each side measure 60 m. find the area of the triangle whose corresponding altitude is 90 meters.

Answer 1

Area of the square=60×60=3600m^2
Since,Area of square=Area of triangle
Therefore,Area of triangle=3600m^2
1/2×b×h=3600m^2
1/2×b×90=3600m^2
b=3600×2/90=80m
So,Area of triangle=3600m^2
Base=80m
