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.

It is impossible to find the area of a triangle with no height, if the triangle had no height it would not even be a triangle, just a angle.

Area = 0.5*Base*Height

Area of a triangle = 0.5*base*perpendicular height

Area of a triangle = 1/2*base*height

Area = 0.5*Base*Height

In order to find the area of a triangle, you need to multiply the base of the triangle with the height of the triangle and then halve your final answer.The formula is (Base x Height) / 2Using that, the area of a triangle can be found.Hope that helps.Jamz159

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.

the height of a triangle is three feet longer than the base. The area of the triangle is 35 square feet. Find the height andbase of the triangle

To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.

Area of a triangle = 0.5*base*perpendicular height

Area of a triangle = 1/2*base*height

It is found by: base = (area*2)/height

base = (2*area)/height

Area = 1/2 * base * height.
