  1. AREA OF PARALLELOGRAM LESSON 19

  2. LETS REVIEW Perimeter of a Square P = 4s Area of a Square A= s2 Perimeter of a Rectangle P = 2L + 2W Area of a Rectangle A= LW or Bh

  3. EXAMPLE 1 Find the Perimeter and Area of the figure. Area of a Square A=s2 A= 32 A=9 m2 3 m. 3 m. Perimeter of a Square P=4s P=4(3) P=12 m

  4. YOU TRY! Find the Perimeter and Area of the figure. 6 m. 6 m.

  5. SOLUTION Find the Perimeter and Area of the figure. Area of a Square A=s2 A= 62 A= 36 m2 6 m. 6 m. Perimeter of a Square P=4s P=4(6) P=24 m

  6. LETS REVIEW PARALLELOGRAM Area of a Parallelogram A=bh Perimeter of a Parallelogram P=2b + 2s Where “b” stands for base and “s” stands for side.

  7. EXAMPLE 2 Find the Perimeter and Area of the figure. 2 cm Perimeter of a Parallelogram P=2b+2s P=2(2) + 2(3) P= 4 + 6 P= 10 cm Area of a Parallelogram A=bh A= 2(2.2) A= 4.4 cm2 3 cm 2.2 cm

  8. YOU TRY! Find the Perimeter and Area of the figure. 5 mm 7 mm 6.5 mm

  9. SOLUTION Find the Perimeter and Area of the figure. 5 mm Perimeter of a Parallelogram P=2b+2s P=2(5) + 2(7) P= 10 + 14 P= 24 cm Area of a Parallelogram A=bh A= 2(6.5) A= 13 cm2 7 mm 6.5 mm
