Answer:
44%
Step-by-step explanation:
in first situation we can find the are by multiplying sides....
area= 15×20=300
after increasing sides by 20% then
20% of 20 cm= 4 cm
20% OF 15 CM= 3 cm
then new sides of rectangle are
20 by adding 4 = 24
15 by adding 3 = 18
then new area of rectangle is 24×18= 432cm²
then for percentage increase we will substract it by first area
432-300=132cm²
132/300× 100 is equal to 44 % it is answer
