P=4s\\
P=72\ in\\
72=4s\\
s=18\
Answer: s = 19 (each side of the square is 19)
Step-by-step explanation:
p = 4s
plug in value for p
76 = 4s
divide by 4
19 = s
each side is 19
To find the length of a side of a square with a perimeter of 76 inches, use the formula for the perimeter, P = 4 s . Dividing the perimeter by 4 gives a side length of 19 inches.
