area = 1/2 base * perpendicular height you can't find both the base and the height if you only know the area

To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.

H = 2 x (A/B)

It is impossible to find the height of a triangle with just it's base.

Area = 0.5*Base*Height

To find the height of a triangle you measure it. It has to be from the middle of the base to the top point.

It is not possible.

You will need to know the height before you can calculate the base form the area.

The relation between the height of a triangle, its base and its area is given by: Area = 0.5 * Base * Height Therefore, we have: Height = (2 * Area)/ Base.

Area = 1/2 * base * height.

Divide the area by height then you get the base.

base = (2*area)/height
