The area of a trapezium is calculated by: Adding the parallel sides. Dividing by 22. Multiplying by the height. This can also be summarised with the following formula: Area Trapezium = a + b 2 × h Area Trapezium = 2a+b × h. Where aa and bb are the parallel sides. Where hh is the perpendicular height of the trapezium.
The area of a trapezium is the number of squares of unit length that can be fit into it and it is measured in square units. The area of trapezium formula is A = ½ (a + b) h. Learn how this formula is derived visually.

Add together the lengths of the bases. The bases are the 2 sides of the trapezoid that are parallel with one another. If you aren’t given the values for the base lengths, then use a ruler to measure each one. Add the 2 lengths together so you have 1 value.[2] X Research source For example, if you find that the top base (b1) is 8 cm and the bottom base (b2) is 13 cm, the total length of the ...Measure the height of the trapezoid. The height of the trapezoid is the distance between the parallel bases. Draw a line between the bases, and use a ruler or other measuring device to find the distance. Write the height down so you don’t forget it later in your calculation.[3] X Research source The length of the angled sides, or the legs of the trapezoid, is not the same as the height. The ...Multiply the total base length and height together. Take the sum of the base lengths you found (b) and the height (h) and multiply them together. Write the product in the appropriate square units for your problem.[4] X Research source In this example, 21 cm x 7 cm = 147 cm2 which reflects the "(b)h" part of the equation.Multiply the product by ½ to find the area of the trapezoid. You can either multiply the product by ½ or divide the product by 2 to get the final area of the trapezoid since the result will be the same. Make sure you label your final answer in square units.[5] X Research source For this example, 147 cm2 / 2 = 73.5 cm2, which is the area (A).If you know the median of the trapezoid, which is a line that runs parallel to the bases through the middle of the shape, then multiply it by the height to get the area.[10] X Research source Thanks Helpful 0 Not Helpful 0- 1M
4 days ago · Area of a Trapezium with a Triangle. Follow these steps to get the formula for the area of a trapezium: Step 1: Divide one of the non-parallel sides of the trapezium into two equal parts. Step 2: Cut out a triangular section from the trapezium. Step 3: Attach this triangular portion to the bottom of the shape.
Jul 13, 2021 · To find the area of a trapezium use the formula, $$Area = \frac{h}{2}(a+b)$$. a and b are the two parallel sides and h is the distance between them. In words, we add the two parallel sides, divide by 2 and multiply this by the distance between the parallel sides.
