Question 1:
If the base of a triangle is increased by 50% and its height is decreased by 50%,
then what will be the effect on its area?
A. 50% decrease
B. 75% decrease
C. 25% decrease
Feedback Area of triangle = (1/2) * base * height
So effect on area = +50 + (-50) + (50)(-50)/100 = -25%
D. 25% increase
