Question

What will happen to the area of rectangle if its length is doubled and breadth is halved

Answer 1

Answer:

originally area will be xy if length is x and breadth is y

now acc to the situation if length is doubled i.e 2x and breadth is half i.e y/2....

area will be l×b

2x ×y/2=xy

area will remain the same i.e xy

follow me and brainlist it

What will happen to the area of rectangle if its length is doubled and breadth is halved?

Let the length be x and breath be y.

As length is doubled so let it be represented as 2x

and breath is half so the breadth can be represented as ½y

Now,

Area of rectangle = l × B

                               = 2x × ½y

                                = x * y

ASSUME

x =5 cm and y = 4 cm

Area = 20 cm²

But if length is doubled and breath is half so,

l = 10 cm and B = 2 cm

Area of rectangle = 10 * 2 = 20 cm

∴ There is NO CHANGE in the area of a rectangle if we double its length and also reduce its width by one-half.
