Answer:
0.4 gallons
Step-by-step explanation:
Length of a bedroom= 20 feet
Breadth of a bedroom= 15 feet
Height of a bedroom= 8 feet
Area of walls of a bedroom= 2(l+b)×h
Area of walls of a bedroom=2(20+15)×8 
Area of walls of a bedroom= 2× 35×8 
Area of walls of a bedroom=560 
Amount of paint in 1 gallon = 400 
Number of gallons required= 
Number of gallons required= 1.4 gallons
Hence, 0.4 extra gallons required
It’s either vertex or base
About 29%.
35 - 25 = 10, or the amount of change
10 / 35 = .285, or the amount of change over total
Answer:
I think 180
Step-by-step explanation:
I think 180 because it looks like M+n are supplimetary angles.
Sorry if this is wrong.
Let
be the dimensions of the rectangle. We know the equations for both area and perimeter:


So, we have the following system:

From the second equation, we can deduce

Plug this in the first equation to get

Refactor as

And solve with the usual quadratic formula to get

Both solutions are feasible, because they're both positive.
If we chose the positive solution, we have

If we choose the negative solution, we have

So, we're just swapping the role of
and
. The two dimensions of the rectangle are
and
