Megan has a piece of fabric which is a right triangular shape. The length of leg 1 is 4 m. The length of the other leg is twice
Bess [88]

Answer:

8.94 m

Step-by-step explanation:

Use the Pythagorean Theorum - a^2 + b^2 = c^2. Use leg 1 as <em>a</em>, leg 2 as <em>b</em>, and the third side as <em>c</em>.

We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

(4)^2 + (4*2)^2 = c^2

Now, we use the Order of Operations to find c^2...

4^2+8^2=c^2\\16+64=c^2\\80=c^2

Now, we find the square root of c^2 to find c...

\sqrt{80} =8.94

So, the length of the third side is 8.94 m.
