help finding the perimter of 78.4 inches whats the length of each side and show me how to work the promblem

1 answer:

6 0

A square has four even sides and the perimeter is equal to the sum of all of the sides.
$P=s+s+s+s=4s$
So we can evaluate the equation for P and then solve for s.
$78.4=4s \\ \frac{78.4}{4} =s \\ s=19.6in$
