Will make brainiest if answer correctly with explanation

a small triangle and a larger triangle are shown below. the two triangles are similar. what is the perimeter of the larger triangle

60

Step-by-step explanation:

The small triangle has a perimeter of 7 inches.

So, since you can fit 3 triangles down the left side of the triangle, you would multiply 7 by 3 to get 21.

Then, since the other side is the same length, multiply 21 by 2 to get 42.

Next, you add 18 to 42 because at the bottom of the picture, it says 18 inches.

That's how you get a perimeter of 60 inches.
