3*4*4=48(см) в квадрате 

Answer 3

Calculating the Area of a Triangle with Sides 3 cm, 4 cm, and 4 cm

To calculate the area of a triangle with sides of 3 cm, 4 cm, and 4 cm, we can use Heron's formula, which states that the area of a triangle with sides of lengths a, b, and c is given by:

Area (A) = √(s(s - a)(s - b)(s - c))

Where s is the semi-perimeter of the triangle, given by:

s = (a + b + c) / 2

Let's calculate the area using these formulas.

First, we calculate the semi-perimeter: s = (3 + 4 + 4) / 2 = 11 / 2 = 5.5 cm

Now, we can use the semi-perimeter to calculate the area: A = √(5.5(5.5 - 3)(5.5 - 4)(5.5 - 4))

A = √(5.5 * 2.5 * 1.5 * 1.5)

A = √(5.5 * 2.5 * 1.5 * 1.5) = √(51.875) ≈ 7.20 cm²

Therefore, the area of the triangle with sides of 3 cm, 4 cm, and 4 cm is approximately 7.20 cm².
