Answer 1

Answer:

MARK AS BRAINLIEST ANSWER

Step-by-step explanation:

Doubling one dimension would double the area, and taking half of one would half the area, doing both at the same time exactly cancels out. ... We now see that there is NO CHANGE in the area A of a rectangle if we double its length and also reduce its width by one-half.

Answer 2

if in a rectangle the length is doubled and breath is half
let the length be x and breath be y
as length is doubled so 2x
and breath is half so ½y
now,
area of rectangle = l × B
= 2x × ½y
now assume x =3cm and y = 2cm
so the real area will be 6cm
but if length is doubled and breath is half so,
l = 6 and B = 1 now area of rectangle
= 6cm
so the area will remain the same
hope it helps you
