Answer:

The length of swimming pool is 10 yards.

Step-by-step explanation:

Given,

Perimeter= 90 feet

Width= 5 yards

As we have to find the length in yards, therefore, we will convert perimeter in yards also.

As we know,

1 Yard = 3 feet

Therefore,

Dividing the perimeter by 3 to convert it into yards.

$90\ feet = \frac{90}{3} \ yards\\90\ feet=30\ yards$

The formula of perimeter of rectangle is;

P= 2(l+w)

Putting values of perimeter and width;

$30=2(l+5)\\30=2l+10\\2l=30-10\\2l=20\\l=\frac{20}{2} \\l=10$

The length of swimming pool is 10 yards.
