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.

The formula of perimeter of rectangle is;
P= 2(l+w)
Putting values of perimeter and width;

The length of swimming pool is 10 yards.
