Question

find the area of rectangle if side of the rectangle are doubled

Answer 1

2( l× b) is theanswer of this questions

Answer 2

Let the Length (l) and breadth (b) of first rectangle.

Then,

• Area of first Rectangle = l × b = lb

Now,

According to Question :-

• Length of new rectangle = 2l

• Breadth of new rectangle = 2b

Then,

Area of new rectangle = 2l × 2b = 4lb.

So,

• From this we conclude that if the side of a rectangle is doubled then area becomes four times .
