area of a triangle = 1/2 base x height ie times the area by two then divide by the base = height
multiply the base by the height
Base area * Height
base times height divide by two
Multiply the area by two then divide by the height - assuming that it is a right angled triangle.
You can find the area of a rectangle by multiplying the base by the height. You can find the area of a triangle by multiplying the base and height, then dividing by two. You can find the area of a cylinder or prism by multiplying the area of the base by the height. You can find the area of a circle by multiplying the radius squared by pi. You can find the area of a pyramaid or cone by multiplying the area of the base by the height, then dividing by three. You can find the area of a sphere by this formula (4/3 pi times radius cubed) you can find the area of a cube by cubing a side.
The height can be found by dividing the area by the sum of the bases and multiplying the result by 2
The formula is: Base times Height divide by two.
I find the area by applying the standard formula for the area of a triangle, which is the length of the base multiplied by the height all divided by two. You should too.
Yes
The area o fa parallelogram is the height (distance between two parallel sides) time then length of a side perpendicular to the height.
