Answer 2

Answer:

The side of the square will be 17cm.

Step-by-step explanation:

Given: The area of a square is 289 cm square.

We have to find the side 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 area of a square is 289 cm square.

The side of the square will be:

$Area= side ^2$

We will put the given value in the above formula;

$=>289=side^2\\=>\sqrt{289} =side\\=>side=17\ \ \ [\because 17\times17=289]$

Hence, the side of the square will be 17cm.
