How do you find the area of a 5 sided shape?
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
What is the total surface area of a triangular prism that has 2 triangles and 3 rectangles?
Work out each area of the 5 faces individually and then add them together.
How to Find square footage of a oddly shaped room?
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.
How do you solve area for symmetric figures?
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.
What is the formula for a triangular pyramid in surface area?
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.
How can you find the area of a polygon that is not one for which you know an area formula?
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
How do you find aras of triangles and parallelograms?
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.
How calculate covered area in feets?
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.
Does pythagoras' theorem work for all triangles?
no only right triangles
Does the Pythagoream Theorem Work on all triangles?
No, only right triangles
What sort of triangles does pythagoras's rule work in?
Right angled triangles.
Triangles are congruent if the have the same?
area
