Rectangular with whole numbers
perimiter=legnth+legnth+width+width=2l+2w
therefor 
p=2l+2w=2(l+w)
p/2=l+w
perimiter=20
20=2l+2w
divide by 2 to make simpler
10=l+w
find all combos
l>w so 
l=9 and w=1
l=8 and w=2
l=7 and w=3
l=6 and w=4
combos
        
             
        
        
        
Answer:

<u><em>The complete question is</em></u>
The first three steps of completing the square to solve the quadratic equation x2 +4x -6= 0, are shown below. 
Step 1: x2 +4x= 6 
Step 2: x2 +4x+4=6+4 
Step 3: (x +2)^2=10 
What are the next 3 steps?
we have
step 4
Take square root both sides

step 5
Simplify

step 6
Solve for x
subtract 2 both sides



 
        
             
        
        
        
Answer:

Step-by-step explanation:
given data;
B = 16m
b =8 m
height   H = 4 m
length  L = 32 m
volume of any right cylinder = (Area of bottom) \times (length)
Volume = A* L
The area of a trapezoid is



therefore volume is given as  
volume = 48*32
