MODULE VI IT’S WHAT’S ON THE INSIDE THAT COUNTS!

2
AREA OF PARALLELOGRAMS To begin talking about the area of parallelograms, we must first know their parts. The base of a parallelogram can be any side. The height is the perpendicular distance between any two parallel bases.

AREA OF PARALLELOGRAMS h b

4
The perimeter of a parallelogram is just the sum of all four sides. The area of a parallelogram is the base times the height.

5
AREA OF PARALLELOGRAMS REMINDER: The area of a triangle is ½ bh. And that makes sense because if you cut a parallelogram in half, it makes two triangles.

6
AREA OF PARALLELOGRAMS Let’s start with an easy one… What is the perimeter of the triangle below? 20 cm 12 cm 14 cm

7
AREA OF PARALLELOGRAMS But what about the perimeter of the shaded triangle below? 9 cm6 cm 8 cm 20 cm

8
AREA OF PARALLELOGRAMS What about this one? What is the area of the shaded region. 25 cm 28 cm7 cm

9
AREA OF PARALLELOGRAMS Knowing what you know about triangles, we can solve for parallelograms much the same way. What is the area of the parallelogram below. 45 10 cm 23 cm

10
AREA OF PARALLELOGRAMS What is the perimeter? 45 10 cm 23 cm

11
AREA OF PARALLELOGRAMS This lesson combines old knowledge with new knowledge. SO THINK OUTSIDE THE BOX!!!
