You are looking for the perimeter of the pool. The perimeter of rectangles can be measured by using the formula 2W + 2L = P (2 * width + 2 * length = perimeter). Using the formula, 2(40) + 2(20) = P, 80 + 40 = P, P = 120. The answer is C. 120 yards.

Answer:

Option C. We need to put 120 yards of fence around the pool.

Solution:

Given that, The length and breadth of the rectangle pool are 40 and 20 yards.

We need to put fence around the pool.  The measure of the fence will be equal to the perimeter of the pool.  The formula for the perimeter of the rectangle is [tex]\bold2\times(l+b)\bold[/tex]

Here l is the length; b is the breadth.

On substituting the values, we get the perimeter of the rectangle.

Therefore, Perimeter [tex]= 2\times(40+20) = (2\times60) = 120[/tex].

So, we need to put 120 yards of fence around the pool.
