Question

The area of a square is 20 m2.What is the length of a side of the square?O A.10 mОВ.20 mC. 5 mD. 10 m

Answer 1

Remember that the formula used to calculate the area of a square is:

`A=s^2`

Where s is the lenght of the side of the square.

This way,

`20=s^2`

Solving for s,

`20=s^2\rightarrow s=\sqrt[]{20}`

Therefore, the lenght of a side of the square is:

`\sqrt[]{20}\text{ m}`
