Answer:
44 percent
Step-by-step explanation:
The sides of the rectangle are 20 cms and 15 cms.
Therefore the area of the rectangle is
20 × 15 = 300 sq. cms.
If each side is increased by 20 percent, the sides will be
20 + 4 = 24 cms and 15 + 3 = 18 cms.
Area of the new rectangle will be 24 × 18 = 432 sq. cms.
Therefore percentage increase in the area will be
(432 - 300) /300 × 100 = 44 percent
