Question

find the area of square of side 4cm. if the side of square is doubled, find the area of resulting new square​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

We know that

Area of square =4×side

=4×4

16cm square

Now,

When we double the side of the square

new side=8

So,

Area of square =4×new side

=4×8

=32cm square

Answer 2

Given: The side of the square is$4cm.$

We have to find the area of the square.

As we know that the formula is used to calculate the area of the square is:  Area $= side ^{2}$

We are solving in the following way:

We have,

The side of the square is$4cm.$

So, the area of the square will be:

Area $= side ^{2}$

$Area = 4^2\\Area =16$

Hence, the area of the square will be$16cm^2$.

Now if the side of the square is doubled, the area of the resulting new square​ will be:

Here the side of the square will be$4\times2=$$8cm.$

Then,

Area $= side ^{2}$

$=>Area=8^2\\=>Area=64cm^2$

Hence, the area of the square will be$64cm^2$.

Hence, we get the area of the square at the side$4cm.$ is$16cm^2$.

And the area of the square at double of that side will be$64cm^2$.
