What is the area of the square that shares a side with the third side of the triangle?

Complete question:

Two sides of a right triangle measure 7 units and 3 units. What is the area of the square that shares a side with the third side of the triangle?

Step-by-step explanation:

Given:

A = 7 units

B = 3 units

To find the length of the third side, let's use Pythagoras theorem.

C² = A² + B²

Substituting figures, we have:

C² = 7² + 3²

C² = 49 + 9

C² = 58

The length of the third side, C is units.

Since the length of the third side is units, the area of the square that shares a side with the third side of the triangle would be C².  

Therefore,  C² =

=

x=0.8898305 is the answer to that equation
