What is the length of side a in the new parallelogram?

2 cm

9cm

90cm

162 cm

You just need to write a proportion between the correspondent sides:

Now, since 45 is 9 times 5, 18 must be 9 times A, and thus A must be 2.

Even if we didn't realize that, we can solve for A the usual way:

A.

Step-by-step explanation:

The person's question up above is A. I'm just putting it short. ;)

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
