Yurrrrrrrrrrr definitely a weird number
Well
<span>
4 x 5 = 20
and
5 x 5 = 25
I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:
6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )
So
6 x 7 = 42
There are faster methods but this is probably the best way to start out.

Answer:
Step 1 : First, solve one linear equation for y in terms of x .
Step 2 : Then substitute that expression for y in the other linear equation. ...
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.
Step-by-step explanation:
To find the length of the room you will have to add up all of the sides and divide by four
