Answer» Step-by-step explanation:AREA of trapezium = 1/2× (sum of parallel sides)×height. height = distance between two parallel sides. for height, draw a prependicular FRON A onCD and make a line on CD such that ABCEis a PARALLELOGRAM (E is the point of line drawn on CD.)now calculate the area of triangle A ED using heron ' formula and then put its value in other formula of area of triangle i.e area of triangle = 1/2 ×base × height through this we get height Now put its value in above trapezium formula HOPE it helps you mark me as a brainliest and don't FORGET to follow.... |
