We will apply Pythagoras theorem in a right triangle, which states

" Consider a right triangle with hypotenuse 'h' and two legs say 'b' and 'p'. Pythagoras theorem states that the square of hypotenuse is equal to the sum of the square of both the legs of a triangle".

Mathematically, $h^{2}=b^{2}+p^{2}$ (Equation 1)

Length of hypotenuse (h)= 52 feet

Length of one leg (let b )= 20 feet

We need to calculate the length of another leg that is 'p'

Using Equation 1,

$h^{2}=b^{2}+p^{2}$

Substituting the values, we get

$(52)^{2}=(20)^{2}+p^{2}$

$2704 = 400+p^{2}$

$p^{2}=2304$

$p=\sqrt{2304}$

p = 48 feet

Therefore, Option D is the correct answer.

Step-by-step explanation:

$x = y \\ 2 \sqrt{14} = x \sqrt{2}$

$x = 2 \sqrt{7}$

$x = y = 2 \sqrt{7}$
