Question

Each side of a rectangle is doubled find the ratio between perimeter of the original rectangle and resulting rectangle Areas of the original rectangle and the resulting rectangle

Answer 1

Ratio of the perimeter is 1:2and the ratio of the area is 1:4

Answer 2

Answer:

Step-by-step explanation:

Let the original rectangle length be l and breadth be b.

New Rectangle length=2l and breadth 2b

original perimeter=2(l+b)

New perimeter=2(2l+2b)=2*2(l+b)

So the ratio of original Perimeter:New Perimeter=1:2

Now,

Area of original rectangle=l*b

Area of new rectangle=2l*2b=4l*b

So, the ratio of area of original to new rectangle is 1:4
