Answer:

A=30u^2

Step-by-step explanation:

Information that we know about the square:

side length: l=\sqrt{30u^2} which can asol be expressed as: l=\sqrt{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=(\sqrt{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
