Answer:option C is the correct answer.
Step-by-step explanation:
The perimeter of a shape or plane figure is the total distance around it. The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
Where a, b and c are the measure of the sides of the triangle.
The lengths of the sides of one triangle are 8 inches, 10 inches, and 12 inches. The shortest side is 8 inches. If a similar triangle has its shorted side as 4 inches, it means that the ratio of each side of the big triangle to the corresponding sides on the small triangle is
8/4 = 2
Therefore, the sides of the small triangle are 4, 5 and 6 inches.
The perimeter of the small triangle would be
Perimeter = 4 + 5 + 6 = 15 inches
