4. Ashley claims that if she triples the side length of a square (s), the area of the square will also be tripled. Do you agree? Explain your thinking. ​

Answer :-

Let the side of the square measure a cm, thus, according to the question,

  • New length = 3(a cm)

We know that,

Area ( Square ) =

Thus, the area of the square with normal length i.e. a cm, will be,

Area = a x a

Area = a²

Now, by taking the new length, the area will become,

Area = 3a x 3a

Area = 9a²

Now,

We observe that, if we divide these, we get,

9a²/a²

( a² will get canceled since its common )

Thus, the ratio becomes,

9 : 1 = Area square with tripled length : Area of square

Thus, the area will increase by 9 times, and not 3.

Hence, Ashley's assumptions are wrong.
