Question

The formula for finding the area of a square that has a side length, s, is A = s2. If a square has an area of 40 square units, what is the length of a side?

Answer 1

The side length of square is
`2√(10)` units.

Explanation:

Given : The formula for finding the area of a square that has side length s is given as
`A=s^2`

Also, given the area of a square is 40 square units.

We have to find the length of the side of square.

Consider the given formula,

`A=s^2`

We are given area s 40 square units

So,
`40=s^2`

Taking square root both sides, we have,

`√(40)=s`

Simplify, we have,

`s=2√(10)` units.

Thus, The side length of square is
`2√(10)` units.

Answer 2

The length of side can be calculated as
s = √40
= √4x10
= 2√10
