A triangle has side lengths of 12 inches 14 inches, and 18 inches. What best represents the perimeter of the triangle in centime
kotykmax [81]

Answer:

111.76 cm

Step-by-step explanation:

The formula for the perimeter of a triangle is given as:

Side A + Side B + Side C

Since our final answer is going to be in centimeters we have to convert the sides from inches to centimeters

Hence:

1 inch ~ 2.54 centimeters

For 12 inches

1 inch = 2.54 cm

12 inches = x

Cross Multiply

x = 12× 2.54 cm

x = 30.48 cm

For 14 inches

1 inch = 2.54 cm

14 inches = x

Cross Multiply

x = 14× 2.54 cm

x = 35.56 cm

For 18 inches

1 inch = 2.54 cm

18 inches = x

Cross Multiply

x = 18× 2.54 cm

x = 45.72 cm

Hence, the perimeter of the triangle

= 30.48 cm + 35.56 cm + 45.72 cm

= 111.76 cm
