Find the perimeter of a square is each side is 3/4 miles long

A square has 4 sides. 
And each of the sides are all the same length. 
3/4 can become 0.75 as a decimal. 
The formula for perimeter is all of the sides added up. 
so we add 0.75 together 4 times. 
Here's the math:)

0.75 + 0.75 + 0.75 + 0.75 = 3

So the perimeter of the square is 3 miles long. 

:P

The total would be 40.53
