- 3. 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 !!
- 4. 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 :
