Lcm is found by finding the factors and making a mega group with all the factors of both groups, excluding repeats from different groups so
12=2 times 2 times 3
18=2 times 3 times 3
megagroup=2 times 2 times 3 times 3=4 times 9=36
the LCM=36

Four points which lie at (0,0) ; (0,2) ; (2,2) ; (2,0)

What is the figure formed?What is the area of the figure?

The given points lie on graph as per the order given in the attachment.
Which shape?
As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.
The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.
<u>Hence! the figure formed is a square.</u>
What is the area?




8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
