Question

if the side of a square is doubled find the ratio of the area of the resulting square to that of the given square​

Answer 1

Step-by-step explanation:

Let initial side of square=a

Area of the square=a^2

If side is doubled

Side of the square=2a

Area of the square=(2a)^2

=4(a)^2

Ratio of areas = 4(a)^2/a^2=4:1

Answer 2

Answer:

1:4

Step-by-step explanation:

let the side be z

area =z×z

=z^2

let the side is doubled

area=2z×2z

=4z^2

So by Comparing

z^2/4z^2

1/4

So 1:4 is the answer
