Question

Write the exact value of the area of a square with a side length of √30 square units? *

Answer 1

`A=30u^2`

Explanation:

Information that we know about the square:

side length:
`l=√(30u^2)` which can asol be expressed as:
`l=√(30)u`

we can use this information to calculate the area by the formula for the area of a square:

`A=l^2`

we subtitute the side length:

`A=(√(30)u )^2`

the square root and the squared exponent cancel each other out (because they are opposite operations) and since this is an area it must have squared units:

`A=30u^2`

The exact value of the area of the square is
`30u^2`
