Answer :

To find the side length of a square field when given its area, we need to understand the relationship between the area and the side length of a square.

The formula for the area of a square is:

[tex]\[ \text{Area} = \text{side} \times \text{side} \][/tex]

or

[tex]\[ \text{Area} = \text{side}^2 \][/tex]

Given that the area of the square field is [tex]\( 1764 \, m^2 \)[/tex], we set up the equation:

[tex]\[ \text{side}^2 = 1764 \][/tex]

To find the side length, we need to take the square root of both sides of the equation:

[tex]\[ \text{side} = \sqrt{1764} \][/tex]

By solving this, we find that:

[tex]\[ \text{side} = 42 \, m \][/tex]

Hence, the side length of the square field is [tex]\( 42 \)[/tex] meters.
