Question

find the area of rectangle if its length and breadth are doubled​

Answer 1

Answer:

If the length is doubled then the new length would be 2L

If the breadth is doubled then the new breadth would be 2B

Step-by-step explanation:

So,

Area when length and breadth are not doubled

L*B=LB=x(Let the total area be x)

When sides are doubled,

2L*2B=4LB=4x

So, the are is four times the previous area when the sides are doubled

Answer 2

Let the length be 2L

Let the breadth be 2B

Area of rectangle = l × b

= 2l × 2b

= 4lb
