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?

20 units squared

Step-by-step explanation:

Use pythagorean theorem to find third side of triangle

Take the sqr root of 20

So the side of the square is sqr root of 20

Area is length x width

The area of a square is 2 times s, where s is the length of one side since a square sides are all equal.

So
