WebThe height = 32 cm. ∴ the area of the parallelogram = base × height. ∴ 256 = base × 32. The base = 256 32 = 8 cm. Example: Find the area of a parallelogram, two adjacent sides of which are 17 cm and 20 cm and their included angle is 60 ∘. Solution: Here, one side b = 17 cm, the other side c = 20 cm, and θ = 60 ∘. ∴ the area = b c ... WebDefinition: The made by two lines with a common vertex When two lines meet at a common point ( vertex) the angle between them is called the included angle. The two lines define the angle. So for example in the figure above we could refer to the angle ∠ ABC as the "included angle of BA and BC". WebThe area of a parallelogram can be calculated when the diagonals and their intersecting angle are known. The formula is given as, area = ½ × d 1 × d 2 sin (x), where 'd1' and 'd2' … easington lane independent methodist church
