Answer:
[tex]A=30u^2[/tex]
Step-by-step explanation:
Information that we know about the square:
side length: [tex]l=\sqrt{30u^2}[/tex] which can asol be expressed as: [tex]l=\sqrt{30}u[/tex]
we can use this information to calculate the area by the formula for the area of a square:
[tex]A=l^2[/tex]
we subtitute the side length:
[tex]A=(\sqrt{30}u )^2[/tex]
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:
[tex]A=30u^2[/tex]
The exact value of the area of the square is [tex]30u^2[/tex]
