Answer:
180 cm2
Area of a polyhedron:
15(=base)x12(=height)
=180cm2
btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.
If so, your ''area of parallelogram'' is 15cm2 since your question is hecking weird.
Btw it's 15cm2 not 15
Please check ur question b4 u ask
The easiest method to draw elevations to the same scale as your floor plans to make the process a bit easier.Tape your main floor plan drawing to the surface of your work table with the front side house facing towards you
First of all calm down and brake down the problem plan a is $25 a month while the other one is $40 you need to subtract to get $15 than divide $15 by $0.25 which you will get 60 but this is not the right answer because its asking you how many phone calls is the cost of plan b less than the cost of plan a so the answer is 59 calls.

To Find : the value of expression 5a.
Solution :
We are given the value of 'a' i.e. a=20
Now to find the value of given expression 5a
⇒
put a = 20 in the equation
⇒
⇒
⇒
Thus , The value of expression 5a when a = 20 is 100
