Question

The equilateral triangle shown has a perimeter of 45 inches. One side is 15 inches. What is the perimeter of the equilateral triangle in feet?

Answer 1

Since the equilateral triangle has all sides of equal length, each side is 15 inches.

To find the total perimeter in inches, we can use the formula:
Perimeter = 3 * side length
Perimeter = 3 * 15
Perimeter = 45 inches

To convert the perimeter from inches to feet, we divide by 12 (since there are 12 inches in a foot):
Perimeter in feet = 45 inches / 12
Perimeter in feet = 3.75 feet

Therefore, the perimeter of the equilateral triangle in feet is 3.75 feet.
