The base of a triangle is increased by 20% and its height is decreased by 15%. What happens to its area?
A. It decreases by 3%
B. It remains the same
C. It decreases by 2%
D. It increases by 2%
E. It increases by 5%
D. It increases by 2%
The new area = the old area ×1.2 × 0.85 = the old area ×1.02. This represents a 2% increase.
