Area = base*height

Base could be 8, and height could be 4. Area for a triangle is 1/2 * base * height. 1/2 * base * height = 16 base * height = 32 Any two factors will work as long as the product is 32.

Knowing just the length of the base you can not work out the area. You need the height and the base or the length of the hypotenuse in order to work out the area.

The area of any triangle is one-half the product of (base times height). Perhaps you can work it out from there.

18 square inches is probably the area of the triangle, not the length of the base. The length of the base would be measured in inches (a unit of length), not square inches (a unit of area). So area = 1 / 2 * base * height = 18 square inches (given) height = 4 * base (given) 1 / 2 * base * 4 * base = 18 square inches 2 * base * base = 18 square inches base * base = 9 square inches base = 3 inches height = 4 * base = 4 * 3 inches = 12 inches Checking our work: height is 4 times the base (12 = 4 * 3) area is 18 (1/2 * 12 * 3).

Base x height divided by 2

The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).The area of such a prism is Bh/3, where B is the base area, and h is the height (perpendicular to the plane that contains the base area).

To work out the area of a triangle, you use the equation, 1/2 base * height... So in this scenario, the area would be: (25m / 2) * 32m = 400m2

Base times height. Just like a rectangle.

The side you use as the base does not matter. What does matter is that the height is the perpendicular distance between this side and the other vertex. If there is a right angle in the triangle, then use the two sides next to it as the base and height. Otherwise a bit of trigonometry will be required to work out the height of the triangle if it is not given.

The area of a rectangle is Base x Height and its the same thing as a parallelogram but the area of a triangle is Base x Height divided by 2 So unless its a parallelogram you just X all the sides.

To work out area of tringle you say half base x height. So if your base was 4 & height was 6 you would say half of 4 which is 2 x by height which is 6 which is 12 (6x2)
