Which equation can be used to find the answer? A playground with four sides has a perimeter of 52 ft. Three of the sides have lengths of 9 ft, 16 ft, and 19 ft. What is the length of the fourth side? A. s – 9 + 16 + 19 = 52 s =26 26 ft B. s + 9 + 16 + 19 = 52 s = 8 8 ft C. s – 52 = 9 + 16 – 19 s = 58 58 ft D. s – 9 – 16 – 19 = 52 s = 96 96 ft

What we know:
Perimeter=52 ft
Perimeter=s1+s2+s3+s4
s1=9ft
s2=16ft
s3=19ft
s4=s

What we need to find: equation for given information and solution to s4=s

Perimeter=s1+s2+s3+s4
52=9+16+19+s

52=9+16+19+s
52=44+s               like terms added
52-44=44-44+s     additive inverse
8=s

Solution: B. s + 9 + 16 + 19 = 52 s = 8 8 ft
