Suppose the base and parallel sides of the trapezium are labelled a and b. Suppose, also, that the distance between a and b is h.
Draw a diagonal.
This will split the trapezium into one triangle whose base is the trapezium's base (a) and another upside-down triangle whose base is the trapezium's top (b).
The heights of both these triangles will be the same as the distance between the parallel sides of the trapezium (h).
The area of the first triangle is 0.5*a*h
The area of the second triangle is 0.5*b*h
So the area of the trapezium = 0.5*a*h + 0.5*b*h = 0.5*(a+b)*h

How can you find the area of a composite figures trapezoid with a triangle?
To find the area of a composite figure consisting of a trapezoid and a triangle, you would first calculate the area of the trapezoid using the formula A = (1/2)h(b1 + b2), where h is the height of the trapezoid and b1 and b2 are the lengths of the two parallel bases. Then, you would calculate the area of the triangle using the formula A = (1/2)bh, where b is the base of the triangle and h is the height. Finally, you would add the areas of the trapezoid and the triangle together to find the total area of the composite figure.

How do you find the volume of a composite shape?
A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.Example 20Find the area of the following composite figure:Solution:The figure can be divided into a rectangle and triangle as shown below.So, the area of the composite figure is 216 cm2.
What is the area of 8 in and 18 in Of composite figures?
There is no information on the shape of the area in question.
How do you find area of polygon composite figures?
You get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.
What is the formula to find volume of a trapezoid?

What is the area of composite figures?
It is the sum of the areas of all the components.
How do you find area of composite figures?
You need to break down the composite figure into simpler shapes whose areas you can calculate using appropriate formule and then add together the areas of all the individual bits.
How can you use the area of a parallelogram to find the area of a corresponding trapezoid?
To find the area of a trapezoid using the area of a corresponding parallelogram, you can draw a line parallel to one of the bases of the trapezoid that extends to form a parallelogram. The area of the parallelogram is calculated using the formula (A = \text{base} \times \text{height}). Since the trapezoid shares the same height and one pair of parallel sides with the parallelogram, you can find the area of the trapezoid by subtracting the area of the triangular sections outside the trapezoid from the area of the parallelogram. This approach effectively utilizes the relationship between the two shapes to derive the trapezoid's area.
Can a trapezoid be divided into rectangle and triangle and have the same formula?
Yes, a trapezoid can be divided into a rectangle and a triangle, and they can share the same area formula. The area of a trapezoid is calculated using the formula ( A = \frac{1}{2}(b_1 + b_2)h ), where ( b_1 ) and ( b_2 ) are the lengths of the parallel sides and ( h ) is the height. When a trapezoid is divided, the rectangle's area can be calculated using its base and height, while the triangle's area can be calculated using its base and height, which can be combined to match the trapezoid's area formula.
How do you find the area or perimeter of composite figures?
Not easily. You need to find the area or perimeter of the components and sum them.
How do you find the area of a trapezoid using the area of a triangle?
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.
