Answer:

B. 90 inches

Step-by-step explanation:

Given that

The length is 50 m

And, the width is 25 m

Scale factor is 3 inches per 5 m

We need to find out the  perimeter of the pool

So,

5 meter = 3 inches

3  ÷ 5 = x ÷ 50

x = 30 inches = length

Now

3  ÷ 5 = x ÷ 50

x = 15 inches = width

Now the perimeter of the pool is

= 2(l + w)

= 2 (30 + 15)

= 90 inches
