540 (100 centimeters = 1 meter, so 54 x 100 = 540.)
        
             
        
        
        
Answer:
26 mm
Step-by-step explanation:
A=wl= 42 mm²
l=7, w= 42/7= 6 mm
P=2(l+w)= 2(7+6)= 26 mm
 
        
             
        
        
        
Use the change-of-basis identity,

to write

Use the product-to-sum identity,

to write

Redistribute the factors on the left side as

and simplify to

Now expand the right side:

Simplify and rewrite using the logarithm properties mentioned earlier.

Answer: If you are reflecting the triangle(or coordinate points in general) off of the x or y axis on the upper quadrants, then the reflection would be negative for x. 
If you are reflecting the triangle(or coordinate points in general) off of the x or y axis on the lower quadrants, then the reflection would be negative for y.
This is because the lower quadrants are usually negative and the upper quadrants are usually positive according to the x axis. The same thing vice verse with y.
These are the rules that I’m guessing your trying to find. Hope this helps!
