Area = 27 mi2
The area of the polygon is 27 mi? What is the length of side
miles

3 mi

Step-by-step explanation:

There are three squares with side a

The area of a square is s^2 where s is the side length

A of the square is a^2

We have three of them so add the areas together

a^2+a^2+a^2 = 3a^2

This is equal to 27

3a^2 = 27

Divide each side by 3

3/3a^2 = 27/3

a^2 = 9

Take the square root of each side

sqrt(a^2) = sqrt(9)

a = 3
