Help me, please.
The area and perimeter of a triangle can be calculated using the following formulas:
Area = (base x height) / 2
Perimeter = a + b + c (where a, b, and c are the lengths of the sides of the triangle)
For example, if the base of the triangle is 5 cm and the height is 3 cm, the area would be (5 x 3) / 2 = 7.5 cm2. The perimeter would be the sum of the lengths of the sides, which would need to be known in order to calculate the perimeter.
