Two equilateral triangles are sitting side-by-side. The length of one side of Triangle A is 5 ft. The sides of Triangle B are 3 times as long as those of Triangle A.

How long is the length of one side of Triangle B?

I wonder what sitting side by side means.

The length of one side of Triangle B can be calculated by multiplying the length of one side of Triangle A by 3.

Let's calculate it step-by-step:

Step 1:
Length of one side of Triangle A = 5 ft.

Step 2:
Multiply the length of one side of Triangle A by 3 to find the length of one side of Triangle B:
Length of one side of Triangle B = 5 ft * 3 = 15 ft.

Therefore, the length of one side of Triangle B is 15 ft.

To find the length of one side of Triangle B, we'll start by finding the length of one side of Triangle A. We know that Triangle A is an equilateral triangle, which means all its sides are equal in length. Given that one side of Triangle A is 5 ft, we can conclude that all the sides of Triangle A are also 5 ft.

Now, let's find the length of one side of Triangle B. We are given that the sides of Triangle B are 3 times as long as those of Triangle A. Since one side of Triangle A is 5 ft, the length of one side of Triangle B is:
5 ft x 3 = 15 ft.

Therefore, the length of one side of Triangle B is 15 ft.
