Answer:
7 ft
Step-by-step explanation:
Perimeter of a rectangle is denoted by the formula: 
, where l is the length and w is the width.
We know that P = 20 and that w = 3. So, let's plug these values in:
Isolate the variable 
by subtracting 6 from both sides and dividing by 2:
Thus, the answer is 7 feet.
Hope this helps!
Answer:
C(50;-20)
Step-by-step explanation:
The question is asking for the midpoint of the line.
The triangle is formed by placing a line directly from the y-axis to the x-axis.
The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].
your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.
Your coordinates for B are (100;0)
C[(x1+x2)/2 ; (y1+y2)/2 ]
C [(0+100)/2 ; (-40+0)/2 ]
C[ 100/2 ; -40/2]
C (50 ; -20)
