Calculate the areas of the triangles by taking the necessary measurements triangles

Calculate the areas of the triangles by taking the necessary measurements triangles with dimensions 1) 6 cm 3 cm 3 cm 2) 4 cm 3 cm 3 cm 3) 4 cm 1 cm 5 mm 4 cm

1) Let’s calculate what the half-perimeter of a triangle is.

P = 6 + 3 + 3 = 12 cm.

p = P / 2 = 12/2 = 6 cm.

Let’s calculate the area of a triangle using its semi-perimeter.

S = √ (p * (p – a) * (p – b) * (p – c)).

S = √ (6 * (6 – 6) * (6 – 3) * (6 – 3)) = √ (6 * 0 * 3 * 3) = * 0 cm².

2) p = (4 + 3 + 3) / 2 = 10/2 = 5 cm.

S = √ (5 * (5 – 4) * (5 – 3) * (5 – 3)) = √ (5 * 1 * 2 * 2) = √20 ≈ 4.47 cm².

3) p = (4 + 1.5 + 4) / 2 = 9.5 / 2 = 4.75 cm.

S = √ (4.75 * (4.75 – 4) * (4.75 – 1.5) * (4.75 – 4)) = √8.68 ≈ 2.95 cm².
