Answer:
The two sides of the triangle are equal so by the property that : If opposite sides of a triangle are equal then the opposite angles are also equal .
Area of triangle = 1/2 multiplied by base and also multiplied by height
A =1/2*b*h
So, we can conclude that the opposite angles are 90 + 90 degrees = 180 degrees (as the angles are equal)
Therefore, c)1/2 *8*3 is right
