add up the cross section and see what vthe answer is, then times it by the other part. Simple!
You simply divide the shape into triangles and work out the area of each triangle (0.5 x B x h) then add up the area of all the triangles
Work out each area of the 5 faces individually and then add them together.
Split the area up into shapes for which you can work out the area: rectangles and triangles. Then the area of the original room is the sum of all the areas.
It depends on the symmetry. Work out the area of half the shape by filling the shape with squares and triangles of known areas and times the answer by two.
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.
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
A regular shape such as a square or rectangle - length times width. If it is an irregular shape, fit known sized squares and triangles within the shape's border and work out area of a square and a triangle times the number of squares and triangles.
no only right triangles
No, only right triangles
