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

Sagot :

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