Perimeter = 2 (width) + 2 (length)
42 = 2(8.5) + 2(length)
Solve for length.

Assuming that the swimming pool is rectangular
Perimeter = 2(Length + Width)
Length + Width = Perimeter/2
Length = (Perimeter/2) - Width
Length = (42/2) - 8.5
Length = 21 - 8.5
Length = 12.5

If the swimmingpool has rectangle shape, we can get the length using this equation, 2(length) + 2(width) = perimeter
2(length) + 2(8.5m) = 42 m
2(length) = 25 m
length = 12.5 m

since you give the width of swimming pool. it must be rectangular. So, for rectangle
Perimer = 2(l + b)
42= 2( l + 8.5)
this implies l= 12.5 m
therefore the length of swimming pool is 12.5 m.

42m/2 - 8.5m
=21m - 8.5m
=12.5m
â´ the length of the swimming pool is 12.5 meters.

Siiggh..
Perimeter = 42 = 2(Length + Breadth)
That is, 2(Length + 8.5) = 42
That is, Length + 8.5 = 21
That is. Length = 12.5
