Question

2 triangles have the same hieght.the base one triangle is twice the other triangle. what is the difference in areas

Answer 1

Height =h of both triangles
Let the base of 1 triangle be x and other be 2x
So area of 1 triangle =1/2*x*h
Area of 2nd triangle =1/2*2x*h
Difference =area of 1 - area of 2nd
1/2*x*h-1/2*2x*h
1/2*x*h(1-x) is the difference
