Question

Two sides of a right triangle measure 7 units and 3 units.

Answer 1

Answer:

20 units squared

Step-by-step explanation:

Use pythagorean theorem to find third side of triangle

${2}^{2} + 4 {}^{2} = {x}^{2}$

$4 + 16 = {20}$

Take the sqr root of 20

$\sqrt{20}$

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

$\sqrt{20} \times \sqrt{20 } = 20$
