Question

If length of rectangle is doubled and breadth
is halved then the new area becomes

Answer 1

Answer:

Same as old area

Step-by-step explanation:

let x be length and y be breadth of old rectangle.

so Area = l*b= xy-----(1)

new length=2x and breadth=y/2

so Area= l*b= 2x*y/2=xy------(2)

from equation 1 and 2

both Areas remain same.

Answer 2

Answer:

Step-by-step explanation:

Area of rectangle =l×b

Is l is doubled =2l

And breadth is halved then b =b/2

Then area =2l×b/2 which is lb

So it remains same
