A swimming pool is three times as long as it is wide. the sidewalk around the pool is 72 yds long. determine the length and width of the pool

Length - 54 yds

Width - 18 yds

Step-by-step explanation:

72 yds = perimeter

3x + x =72

4x = 72

Since 4x equals 72, you would divide 72 by 4 to find out how much x equals.

72/4 = 18 yds

18 yds = width

Since the length is three times as long as the width, you would multiply 18 by 3.

18 x 3 = 54

54 yds = length

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

the answer to your question a or b but i am pretty sure it is b. i hope this : )
