what do you want to measure? the area? If so you need a/2 multiplied by the base multiplied by the height. 1/2bh

All the angles are smaller than 90o, so triangle is acute triangle.
The formula to calculate the area of a triangle is A = 1/2 * base * height, where A represents the area, the base is the length of the triangle's base, and the height is the perpendicular distance from the base to the opposite vertex. This formula is derived from the fact that the area of a triangle is half the product of its base and height. By plugging in the values for the base and height into the formula, you can easily determine the area of the triangle.
If all the sides are equal to 5 cm, then it's a equilateral triangle. An equilateral triangle is a triangle in which all the sides are equal.
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
