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 ...
WebThe kite is divided into two congruent triangles by the longer diagonal. The longer diagonal bisects the pair of opposite angles. The area of kite = 12× d1× d2, where d1, d2 are lengths of diagonals. Perimeter of a kite with sides a and b is given by 2 [a+b]. The sum of the interior angles of a kite = 360°.
WebAngle A and Angle B are two interior angles of the parallelogram. Formula 1: For any parallelogram, the formula for the length of the diagonals is expressed as: \(p = \sqrt{x^2 + y^2 - 2xy \cos A} = \sqrt{x^2 + y^2 + 2xy \cos B} \) ...
