Question

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

Answer 1

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 $30u^2$
