Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
half of the base multipled by the height
Half of the base times height.
Yes.
For all triangles: area = 1/2 * base * height
The title of the formula is "Formula for the Area of a Triangle". No discrimination is expressed or implied.
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
Surface area of a globe = 4*pi*radius2
half of the base multipled by the height
Half of the base times height.
A=1/2 base x height
Yes.
For all triangles: area = 1/2 * base * height
There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but no a volume.
A=1/2bh The area of a triangle is 1/2bh. If the base of it is a triangle and all 4 of the triangles aren't the same, then you have to find the area of the base triangle and then the three other triangles (which should all have the same area). If all four of the triangles have the same area, then just find the area of one of the triangles and multiply that by four. A triangular pyramid that has four equal triangles is also called a tetrahedron.
There is no general formula.Divide the heptagon into triangles.Calculate the area of each triangle.Sum the areas of the triangles.
There is no simple formula. You need to divide it into triangles, calculate the areas of each one and sum the results.
