Answer:
the answer is [tex]\sqrt 8[/tex], or 2.83 cm.
Step-by-step explanation:
You need to use the pythagorean theorem to solve this. It states that [tex]a^{2} + b^{2} = c^{2}[/tex]. a is one leg of the triangle, b is the other leg, and c is the hypotenuse (the slanted line that connects them). We need to do [tex]2^{2}[/tex] to find this. Since [tex]2^{2}[/tex] is 4, we know both legs are 4 [tex]cm^{2}[/tex]. 4 + 4 = 8. Since c is squared, we need to find the square root of 8, or just leave it as is. the final answer is [tex]\sqrt{8}[/tex], or 2.83. Hope this helped! :]
