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.
[tex]90\ feet = \frac{90}{3} \ yards\\90\ feet=30\ yards[/tex]
The formula of perimeter of rectangle is;
P= 2(l+w)
Putting values of perimeter and width;
[tex]30=2(l+5)\\30=2l+10\\2l=30-10\\2l=20\\l=\frac{20}{2} \\l=10[/tex]
The length of swimming pool is 10 yards.
