Answer 1

Answer:252

Explanation:

Previous length=10

Previous width=20

20% of previous length

20% of 10

20/100 x 10

(20 x 10)/100

200/100=2

Previous length increased by 20%=10+2=12

New length=12

5% of previous width

5% of 20

5/100 x 20

(5x20)/100

100/100=1

Previous width increased by 5%=20+1=21

new width=21

Area of enlarged rectangle=new length x new width

Area of enlarged rectangle=12 x 21

Area of enlarged rectangle=252
