<u>Answer</u><u> </u><u>:</u><u>-</u>
Let the side of the square measure a cm, thus, according to the question,
We know that,
➭ Area ( Square ) = a²
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.
