Question

if the length and breadth of a rectangle are increased by 20% then what would be the percent increase in the area of the rectangle​

Answer 1

Answer:

4%

Step-by-step explanation:

20L/100=0.2L= L'

20B/100=0.2B = B'

A=L*B

A'=L' * B'

A'=0.2*0.2*(L*B)

A'=0.04*A

0.04 in percentage is 4%
