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

I just helped with this one?

Answer 2

well, when finding perimeter, you add all the sides together, so to find one side you're going to subtract all the given sides from the total perimeter. so:
52-16-19-9=s then simplify.
s=8
once you've simplified you can double check by adding 8+19+16+9 together and seeing if it equals 52

Answer 3

answer is b

Answer 4

if you add up 9+16+9 it gives u 44 subtract that from 52 and you get 8 so s=8
