Question

Find the area of a parallelogram with the base of 13 units and a height of 24 units.

A) 312 units <-- Squared
B) 156 units2 <-- Squared
C) 312 units
D) 156 units


I THINK IT'S C, but I don't know if it's squared or not.

Answer 1

It should be squared. Can you guess why?

Answer 2

Can you help me understand how to tell if it's squared? I understand everything else but I don't understand how to tell if the problems are squared.

Answer 3

Lets say the side of a square is 5 m.
Imagine metres(m) is a variable like x.
So to get the area you would multiply.
5 m * 5 m \
What will you get?

Answer 4

Are you there @Ruhhr ?

Answer 5

You get 10 right?

Answer 6

No!! its 5 m * 5 m.

Answer 7

Yeah sorry, school computer is kind of messed up.

Answer 8

25

Answer 9

Don't exclude m. As I said, take it as a variable.

Answer 10

Suppose you're simplifying an expression(5m * 5m).
What would you do?

Answer 11

Idek " * " means...

Answer 12

* means multiply. So the side of the square is 5 m. Take m as a variable.
Area is 5m * 5m. How would you write this?

Answer 13

Are you there?

Answer 14

I said 25 is the answer.. if its not then idk how to do it. I have not learned this stuff, I have to take an online class. I don't have a teacher in front of me teaching me this so it's alot difficult t know these things.

Answer 15

You know algebra right? Multiplying monomials?

Answer 16

5 x 5 = 25, I said that already

Answer 17

I know I'm asking you something different. Look at my question properly. I asked what is 5m * 5m. m means metres, to indicate the unit of the side of the square.

Answer 18

I give up.. idk

Answer 19

Thanks for your help.

Answer 20

If m is a variable, then it can have any value.
While writing units for sums like this, then we take m(meters) as a variable.
So basically, if m is a variable, then you have to consider m while multiplying 5m * 5m, because m is also a number.
So 5m * 5m would be equal to 5 * 5 * m * m
= 25m^2.
We always write the unit for area as 'squared' because of this reason. We would write the area of a square whose side is 5 m(meters) as:
\[25m ^{2}\]
get it?
