  " 7√6 " .

                →   The answer is:  " 7√6 units " .

Step-by-step explanation:

Method 1:

This will be a "45-45-90" triangle;

which means that in:

(two sides for triangle will be the same).

which is consistent with the information give:

(the two side of the triangle are sides of a "square" ,

 and ALL sides of a square have the "square length" ;

and one side with be 90 degrees (a right triangle);

and the other angles will be 45 degrees (which is 1/2 of 90 degrees because the will cut into "1/2" of each of the "two other 90 degree angles" when a diagonal is drawn to form the "hypotenuse".

So, for "45-45-90" triangles, the side lengths, are:  

     "x, x, x√2 " ;  in which "x√2" represents the side length of the "hypotenuse" ;  and the two "x" values represent the equal values for the other 2 (two) side lengths.,

We are asked to find the "diagonal" of the square;  in which:  "x = 7√3" ;

 That is, we are ask to find the hypotenuse:  "x√3"  ;

 Note:  We are given:  " x = 7√3 " ;

So:  " x√3 " =  " 7 *√3 *√2 = 7 *√6 = " 7√6 ".

The answer is:  " 7√6 units " .

Method 2:

Use the Pythagorean theorem (for right triangles):

 "  a² + b² = c² " ;  

      in which: "c" represents the "side length" of the "hypotenuse" ;

                or:  the "diagonal" of the "square" ; for which we shall solve.

                      "a" and "b" represent the other sides of the right triangle.

                     In this case, "a" and "b" are equal;

                            since "a" & "b" are the side lengths of a square.

                    We are given:  a = b = " 7√3 " .

                      We are to find "c" .

"  a² + b² = c²  " ;  

↔   " c²  = a² + b²  " ;

 →  c²  = (7√3)² + (7√3)²  ;

 →  c²  = (7²) * (√3)² + (7²) (*√3)²  ;

 →  c²  = ( 49*3)    +  (49*3) ;

 →  c²  = (147) + (147) ;

 →  c²  = 294 ;

Take the "positive" square root of each side of the equation;

    to solve for "c" ;

 →  ⁺ √(c²) = ⁺ √294 ;

→  c = ⁺ √294

⁺ √294 =  ⁺ √3 ⁺ √98 ;

                         →   √98 = ⁺ √49⁺ √2 ;

⁺ √294  =  7√3√2  =  7√6 .    

  c = 7√6

The answer is:  " 7√6 units " .
