  1. 1. INNOVATIVE LESSON PLAN RENJINI K.R B.Ed MATHEMATICS REG NO: 13304009
  2. 2. Area of Parallelograms Standard 8
  3. 3. Goal Find the area of parallelograms.
  4. 4. Key Vocabulary Base of a parallelogram Height of a parallelogram Parallelogram Rhombus
  5. 5. Parallelogram A parallelogram is a quadrilateral where the opposite sides are congruent and parallel. A rectangle is a type of parallelogram, but we often see parallelograms that are not rectangles (parallelograms without right angles).
  6. 6. The Base of a Parallelogram Either pair of parallel sides of a parallelogram are called the bases of the parallelogram. base base
  7. 7. The Height of a Parallelogram The shortest distance (perpendicular distance) between the bases of a parallelogram is called the height of the parallelogram. The height of the parallelogram is always perpendicular to the bases.
  8. 8. Area of Parallelogram What is the area of this parallelogram? b=base h=height
  9. 9. Area of Parallelogram What is the area of this parallelogram? b=base CUT HERE! h=height
  10. 10. Area of Parallelogram What is the area of this parallelogram? MOVE TO HERE! b=base h=height
  11. 11. Area of Parallelogram It’s the same as the area of this rectangle h=height b=base
  12. 12. Area of Parallelogram Arearectangle= base x height (perpendicular height h) h=height b=base
  13. 13. Area of Parallelogram Areaparallelogram = base x height (perpendicular height h) b=base h=height
  14. 14. Area of Parallelogram b h Words: Area =(base)(height) Symbols: A = bh Very Important: The height must be perpendicular to the base.
  15. 15. Example 1 Find the Area of a Parallelogram Find the area of the parallelogram. SOLUTION Use the formula for the area of a parallelogram. Substitute 9 for b and 6 for h. A = bh Formula for the area of a parallelogram = (9)(6) Substitute 9 for b and 6 for h. = 54 Multiply. The parallelogram has an area of 54 square meters. ANSWER
