Hello ! My Name is Jake Russell B. Lira , and

welcome again to my module in Mathematics about

finding the areas of the given figure by usin g the

formula .

My module consists of activities and exercises to help

you understand clearly . So I hope that you like it too,

like my past module !!

Have fun and enjoy !!

AREA OF PARALLEOGRAMS

A C

A Figure with

B D

A Figure with two parallel sides is a PARALLEOGRAM .

Formula : A=bxh or A=bh

Example : Base = 7cm

Height = 3cm

A = 7cmx3cm

A = 21 cm

Two straight lines are said to be parallel when they do not meet.

AC is Parallel to BD.

AB is Parallel to CD.

AREA OF A TRAPEZOiD

A B

C D

The distance between the upper and lower bases in figure A is it’s Height.

Side AB And CD are called Bases.

Example :
