Question

the side of a square is 5 cm if its side is doubled what is the area of the new square how many times is the area of the new square bigger than the area of the old square​

Answer 1

Answer:

Area- 100cm2

4 times bigger

Step-by-step explanation:

Imagine a square which has a side-length of 5. To find its area, we would have to multiply the length times its height, which, as all sides of a square are the same, would be 5x5 which equals 25cm2

If we doubled the side-length, our side would be 10cm long and consequently, the sides would be 10x10=100cm2

Now we should do a ratio-

100:25=4:1

For every 1 small square, the other one will be 4 times bigger.
