Question

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.

Answer 1

Answer:
`s = √(81)`

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

81 = s^2

`√(81) = \sqrt{s^(2) }`

s =
`√(81)`

Answer 2

Option 2nd is correct

`s = √(81)` inches

Explanation:

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

`A=s^2` ....[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;

`s^2 = 81`

⇒
`s =\pm √(81)`

∵Side of square cannot be in negative.

⇒
`s = √(81)` inches

Therefore:

A square has an area of 81 square inches →
`s = √(81)` in
