Solution:
To find the perimeter of a triangle, you simply add up the lengths of all three sides. Since the triangle in question has each side measuring 0.75 inches, you'd calculate the perimeter as follows:Perimeter = side_1 + side_2 + side_3Perimeter = 0.75 inches + 0.75 inches + 0.75 inchesPerimeter = 3 * 0.75 inchesPerimeter = 2.25 inchesSo, the perimeter of the triangle is 2.25 inches. The correct answer to the question in the image is 2.25 inches.
