see?

3. Give the characteristics of a
rectangle.

4. Rectangle
• It is a quadrilateral.
• It has two opposite equal
sides.
• It has two dimensions the
length and width.

5. How do we find the area of
this rectangle?

6. To find the area of
the rectangle :
• Use the formula
Area= Length x Width

7. * By means of counting
the squares inside the
plane figure.

8. Find the area of the
following rectangles.
A = 28 sq. units

9. A= 12 sq. units A= 32 sq. units

10. A= 15 cm² A = 60 cm²

11. What figure do you
see?

15. Dino saw a picture of an interesting
building in a post card. He was
interested to find the area of the
parallelogram-shaped façade of the
building.He remembered that
parallelogram was discussed in their
Math class.Help Dino find the area.

16. *What can you say about the
picture that Dino saw in the post
card?
*If we have a beautiful sight like
what Dino saw in the post card how
are we going to maintain its beauty?

18. How can we help Dino find the area
of the parallelogram facade of the
building?

20. *Each group shall write the
steps in finding the area of the
assigned figure.
* Outputs shall be posted for
presentation.

21. * How did you find the activity?
* How were you able to find the area of the
figure assigned to your group?
* In how many ways were you able to find
the area?
* Were you able to use any of your
previous learning?

22. How do we find the area of a
parallelogram?
The area of a parallelogram can be
completed by using the formula
Area of parallelogram= base x height

23. *If A is the area of the parallelogram,
b is its base, and h is its height, then
A = b x h
* Express the answer in terms of
square units / ( cm²,dm², m²)
