You have to cut the trapezoid into three shapes. The three shapes will be two triangles and one rectangle or square. You have to find the area of these three shapes and then add all of the three areas up to find the area of the trapezoid.

How can you find the area of a composite figures trapezoid with a triangle?
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
How do you find the perimeter of a right angled triangle using the area?

What is the area of a trapezoid with base of 4Cm and 28Cm?
The height of the trapezoid is also needed to find its area which is as follows:- Area of a trapezoid = 0.5*(sum of bases or parallel sides)*height
How you could find the height of a trapezoid if you knew the length of the 2 bases and the area of the trapezoid?
Height of trapezoid = 2*area/sum of parallel sides
How do you find the angle measures of a trapezoid?
A trapezoid is a 4-sided shape, therefore the sum of the angles adds to 360 degrees. if you continue the lines until they touch you have a triangle, whose angles sum to 180 degrees. using the law of sines, the ratio of length of a side to the sine of the angle opposite of a triangle is consistent for all three sides. using the law of cosines you are able to find the angle between any two lengths of a triangle. use these two laws to find the bottom two angles which form the base of the triangle. the remaining two angles can be found by finding the angles in the triangle that sits on top of the trapezoid, and determining their compliment angle 180 - angle = compliment angle

How do you find the area of a trapazoid?
To find the area of a trapezoid you have to use the equations: [Height divided by 2] x [base1+base2] and the answer you get is the area of the trapezoid.
How do you find trhe area of a triangle using fractions?
The answer will depend on the shape of the triangle and what is known about it.
How do you find the area of a triangle using cotangent?
(c2) / (2 cot A + cot B) = Area of Triangle ABC
How do you find the area for the trapezoid?

How do you find an area of trapezoid?
Area of a trapezoid: 0.5*(sum of its parallel sides)*height
Given the sides of a triangle how do you find the height?
By using sides we get area of triangle and then using (1/2)heightxbase we get height.
Calculate surface area of a prism?
To find the SA of any prism, find the area of each face. (*Note: Depending on the shape of the face, there might be different formulas. Area of Square=length x length Area of Triangle=base x height divided by 2 Area of Trapezoid=A1+A2 (divide the trapezoid into two triangles and find the area of each triangle, then add them) ) After you find the areas of all the faces of the prism, add all the areas to get the SA.
