WebJan 19, 2024 · The height determines where the similar triangle is cut off to give the trapezium. Thus, if we let the base you want be b, and the other B, then it follows that b B = a A. You can determine A, the height of the main triangle, from the given information. Webwe know that area of isosceles trapezoid = (sum of parallel sides ÷ 2) × height. therefore, 128 = [ (12 + 20) ÷ 2] × height. Height = 128/16 = 8 inches. Example 2: Find the area of an … WebTo find the area of a trapezoid, perform the following calculations: Add the lengths of the 2 bases (parallel sides) Divide by 2 to get the average length of the bases. Multiply this by the height (distance between the parallel sides) For example, a trapezoid with bases of 4cm and 2cm and a height of 5cm has an area which is calculated as: race and disability canada
