Question

The base and height of a triangle are in the ratio 4:5. If the area of the triangle is 90m2,find the measures of its base and height.

Answer 1

Let the base of the triangle be 4x and height be 5x
Area of triangle=1/2*base*height
90=1/2*4x*5x
90*2=20x^2
x^2=9/1
x=3
So height is 5x=5*3=15m
Base=4x=4*3=12m
