| Let us calculate how many centimeters the value of the perimeter of the designated figure is equivalent to when it is known, in accordance with the data from the conditions of this assignment, that the side is sixty-eight centimeters, and the base is one hundred twenty centimeters:

120 + (68 * 2) = 256.

Let’s calculate what will be equal to half of the perimeter of this figure:

256: 2 = 128.

Let’s calculate how many cm2 the area of the triangle will be:

S = √128 (128 – 120) (128 – 68) (128 – 68) = 1920.

Answer: 1920 cm2.
