Find the perimeter of a triangle with sides a, b and c, if a = 140 cm; b = 125 cm and c = 101 cm.

The perimeter of a triangle is calculated by adding the lengths of its three sides.

We write down the formula for determining the perimeter of a triangle:

P = a + b + c;

P is the perimeter of the triangle;

a, b and c – the lengths of the sides of the figure.

Substitute the value of the lengths of the sides in the formula and find the perimeter of the triangle;

P = 140 cm + 125 cm + 101 cm = 366 cm.

Answer: The perimeter of the triangle is 366 cm.
