i think basexheight and then divide 2
To calculate the area of a triangle - divide the length of the base by 2, then multiply that figure by the height. If the measurements are in centimetres, once you have your area - multiply your figure by 100 and you'll have the area in millimetres.
You first multiply the length and the width, the you divide it by 2.
The formula is A=1/2bh b=base of triangle h=height of triangle A=area 1/2=divide base times height by 2
the formula for area of a triangle is one half base times heightA = 1/2 * base * heightIf you know the area and height, divide the area by 2 times the height.b = a/2h
1/2bh b=base h=height To find the are of a triangle,you have to multiply the base times height and divide the answer by 2. To find the area of a triangle you need to multiply all the sides of the triangle and then divide by 2.
To find the area of a triangle, multiply base x height and divide by two. Written as: A=bh/2
Only for the area of a triangle. A= bh/2 (base times height divided by 2)
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.
Multiply the area by 2 and divide by the base

lenght x width, then divide by 2
Lenght X Width, then you divide the number by 2.
So, you divide the base by 2. Then, you divide the area by that answer and you'll find the height.

(13x9) / 2 Length times width. Divide by 2
