Answer: total length of frame material is 3.2 meters
Step-by-step explanation:
The perimeter of an object or a plane shape is the distance around the object of plane shape.
Mila plans to frame a poster she bought at a concert. The total length of frame material that she needs would be the perimeter of the rectangular frame. The formula for determining the perimeter of a rectangle is expressed as 
Perimeter = 2(length + width)
The frame will be rectangular with a base of 0.65 meters and a height of 0.95 meters. Therefore, 
Perimeter = 2(0.65 + 0.95)
= 3.2 meters
 
        
             
        
        
        
Let's split it up to make it a little easier. 
There's 50 minutes plus another 5 minutes that needs to be added to 11:55
Now, if we add the 5 minutes to 11:55, it becomes 12:00
And we simply have to add the other 50 minutes to 12:00, making it 
12:50
So, 55 minutes later than 11:55 is 12:50
        
                    
             
        
        
        
The answer is 33.............
