Question

2 The sides of a rectangle are 20 cm and 15 cm. If each side is increased by 20%, find
the percentage increase in the area.​

Answer 1

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
