The area of a square can be found using the equation a= s2, where a is the area and s is the measure of one side of the square. match the equation for how to slice for the side length of a square to its description.

Step-by-step explanation: A= s^2, A = 81

81 = s^2

s =

Option 2nd is correct

inches

Step-by-step explanation:

The area of a square can be found using the equation:

              ....[1]

where,

A is the area of square

s is the measure of one side of the square.

Given that:

A square has an area of 81 square inches.

⇒A = 81

Substitute in [1] we have;

⇒

∵Side of square cannot be in negative.

⇒ inches

Therefore:

A square has an area of 81 square inches → in
