Answer:
D
Step-by-step explanation:
The question states you need a square. That means whatever you do, must leave a square number like 49 or 64
If you add 6 or 7 to 56 you do not get 64 A and C are both wrong.
If you subtract 7 from 56 you get 49 which is a perfect square and all 4 sides will equal 7.

Quadrilateral</h3>
A quadrilateral is a polygon that has four sides and four angles. The sum of interior angles in a quadrilateral is 360°. Types of quadrilateral are square, rectangle, rhombus, kite and so on.
Let x represent the length of the third side, hence:
x = 5 + (5 * sin(20)) + (5 * sin(10)) = 7.5 cm
The length of the third side of the quadrilateral is 7.5 cm.
