Two sides of a triangle are 12 cm and 14 cm. The perimeter of the triangle is 36 cm. What is its third side?

Two sides of a triangle are 12 cm and 14 cm. The perimeter of the triangle is 36 cm. What is its third side?

To find the third side of the triangle when two sides are 12 cm and 14 cm, and the perimeter is 36 cm, you can use the formula for the perimeter of a triangle, which is the sum of all three sides:

Perimeter = Side1 + Side2 + Side3

In this case, you're given the perimeter (36 cm), Side1 (12 cm), and Side2 (14 cm). Now, you can solve for Side3:

36 cm = 12 cm + 14 cm + Side3

Now, isolate Side3:

Side3 = 36 cm - (12 cm + 14 cm) Side3 = 36 cm - 26 cm Side3 = 10 cm

So, the third side of the triangle is 10 cm.
