The lengths of the sides of one triangle are 8 inches,

10 inches, and 12 inches. What is the perimeter in inches

of a similar triangle whose shortest side is 4 inches?

A-10

B-12

C-15

D-30

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
