Answer:

x = 4

Step-by-step explanation:

Since the triangles are similar, you know that the sides are equally proportional to all the other ones.

What I do is set up two fractions:

\frac{2}{3} = \frac{x}{x + 2}

Make sure that the bigger sides are on the same side of the fraction as each other!

Now, you solve for x.

2(x + 2) = 3x

2x + 4 = 3x

-x + 4 = 0

x = 4

I hope this helps!

Length = 4+ 2(56)

<u>Length = 116</u>

<u>Width = 56</u>

CHECK YOUR WORK
