Answer:
a1 = 1/4
a2 = 1/2
a3 = 3/4
a4 = 1
Step-by-step explanation:
an = a/n
then when a= 1, 2, 3, 4
a1 = 1/4
a2 = 2/4 = 1/2
a3 = 3/4
a4 = 4/4 = 1
The least common multiple of 9 and 21 is 63

The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:

Then, finding CB by Pythagorean Theorem:

And:

Therefore:
