Given : a parallelogram, ABCD when AB=15cm and BC=10 cm
DE=12cm
To Find : Area
Perimeter
Solution:
Opposite sides of parallelogram area equal
Hence perimeter = 2 ( sum of adjacent sides)
=> Perimeter = 2 ( AB + BC)
=> Perimeter = 2 ( 15 + 10)
=> Perimeter = 50 cm
Area = Base * corresponding height
=> Area = BE * DE
=> Area = 10 * 12 = 120 cm²
Perimeter = 50 cm
Area = 120 cm²
