the surface area of the trapezoid =(h/2)*(b1+b2) the unit is cm2
* * * * *
Not particularly helpful when h, b1 and b2 are undefined. And not even true if these lengths are measured in inches!
If a and b are the lengths of the parallel sides and h is the perpendicular distance between them, then Area = (a + b)*h/2 measure in appropriate square units.
A trapezoid has 2 inner triangles and so work out the area of each triangle then add them together. Alternatively use the formula for area of a trapezoid which is:- 0.5*(sum of parallel sides)*height
Total surface area = (2*pi*radius2)+(pi*diameter*height)
Formula for surface of sphere is 4 X pi X radius squared.4 x 4squared = 64 pie = 201.0622498so your answer is64 pie or 201.0622498(Either would work)
No because 90 degrees and 180, 270 degrees don't work for the trapezoid
1 - (a+b) X h 2
A trapezoid has 2 inner triangles and so work out the area of each triangle then add them together. Alternatively use the formula for area of a trapezoid which is:- 0.5*(sum of parallel sides)*height
A quadrilateral does not have a surface area because it is not a voluminous figure.
The formula for the area of a parallelogram is: base*perpendicular height = area and in this case it is 18,532 square meters. But it's interesting to note that the formula for the area of a trapezoid will work out perfectly well for the area of any quadrilateral that has parallel sides. For instance insert the dimensions of the parallelogram in question into the trapezoid formula: 1/2*(226+226)*82 = 18,532 square meters.
The two parallel sides are called the bases, and the two non-parallel sides are the legs. If you call any other pair of sides the bases, the formula for the area of the trapezoid will no longer work.
Work out each figure separately then add them together: Area of a trapezoid = 0.5*(sum of parallel bases)*height Area of a rectangle = length*height
Calculus can be used to find the surface area of any object given that you know the equation describing said object. It's usually easier to find the area from experiment or through using a combination of existing models to approximate the surface area
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
It says so in the formula
Area = base*height
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
