B. Motivation
Before we proceed to our discussion this morning, let’s answer
first the activity I prepared for you.
Direction: Find the ten words in the grid below.

E L A R S K D C P L B N
I Y D H U C A D J M N G
G I I G B I H T G N E L

B H U B R E T E M A I D
C. Unlocking of Difficulties
Okay very good!
Now, letus define these words that we’re going to encounter
later.
 Height (h) - the distance from a top corner to the
opposite side called base (b). A triangle, a rhombus, a
parallelogram, and a trapezium have height(h). The
heightis always perpendicular to the base; in other
words, the height makes a "right angle" with the base.
 Length (l) – commonly used instead ofbase for
square and rectangle.
 Width (w) – commonly used instead ofheightfor
square and rectangle.
 Diameter (d) – the distance from one pointofa circle
to another pointofa circle which passes through the
center of the circle.
c. Lesson Proper
Now, we’re going to tackle Perform estimation and basic
calculation.
It is important to be able to measure and calculate surface
areas. It might be necessary to calculate, for example, the
surface area ofthe cross-section ofa canal or the surface area
of a farm. The mostcommon surface areas are triangle,
rectangle, square, circle, rhombus,parallelogram, and
trapezium.
TRIANGLE The surface area or surface (A) ofa triangle is
calculated by the formula:
A (triangle) = 0.5 x base (b) x height (h)
Triangles can have many shapes butthe same formula is used
for all ofthem.
SQUARES AND RECTANGLES The surface area or surface
(A) of a square or a rectangle is calculated by the formula:
A (square or rectangle) = length (l) x width (w)

3. In a square the lengths of all four sides are equal and all four
angles are right angles. In a rectangle, the lengths ofthe
opposite sides are equal, and all four angles are right angles.
RHOMBUSES AND PARALLELOGRAMS The surface area
or surface (A) of a rhombus or a parallelogram is calculated by
the formula:
A (rhombus or parallelogram) = base (b) x height(h)
In a rhombus, the lengths ofall four sides are equal; none of
the angles are right angles; opposite sides run parallel.
In a parallelogram the lengths ofthe opposite sides are equal;
none ofthe angles are right angles; opposite sides run parallel.
D. Generalization
I know you’ve learned a lotfrom today’s Discussion, so
anyone who can give the formula of the following:
 Triangle
 Squares and rectangles
 Rhombuses and parallelograms
Application
Direction: Study the figures below and calculate its surface
area by identifying first what is the value of its base and height
or length and width. Write your answer on a separate sheetof
paper.
