Length of AF = 7 cm
Step-by-step explanation:
Area of Parallelogram ABCD = AE * CD
AE = 5.6 cm
CD = AB = 20 cm
Area of Parallelogram ABCD = 5.6 * 20 = 112 cm²
Area of Parallelogram ABCD = AF * BC
AF = ?
BC = 16 cm
=> Area of Parallelogram ABCD = AF * 16
AF * 16 = 112
=> AF = 7 cm
Length of AF = 7 cm
