Question

if the height of triangle decreased by 20% and base is increased by 20% what will be the percentage change in area​

Answer 1

Answer:

yes

Step-by-step explanation:

suppose

b=10 h=10

$= \frac{1}{2} \times b \times h \\ = \frac{1}{2} \times 10 \times 10 \\ \\ = 5 \times 10 \\ = 50$

if breadth increases 20% and height decreases 20%

$= \frac{1}{2} \times 12 \times 8 \\ = 6 \times 8 \\ = 48$

coparing to 1st one 2nd is less than 1st one
