Answer 2

$\LARGE{ \underline{\underline{ \tt{Required \: answer:}}}}$

The above quadrilateral is a square because of the marking shown for the equilaterality of sides.

We have,

• Side of the square = 13

We need to find:

• Variable x and y?

Solution:

x is the side of the square and y is the diagonal. Hence,

$\large{ \boxed{ \sf{x = 13}}}$

And for finding the diagonal which can use the Pythagoras theoram where the leg sides (p and b) are the sides of the triangle. Hence,

➝ y = √13² + 13²

➝ y = √338.

$\large{ \boxed{ \sf{y = 13 \sqrt{2} }}}$

The correct option is Option (D)
