If you wanted to paint the entire door (even the top and bottom which people don't usually paint)
the surface area is
SA=2(LW+LH+WH)
where L=length, W=width and H=height
given
L=35.25
W=1.75
H=77
SA=2(35.25*1.75+35.25*77+1.75*77)
SA=2(61.6875+2714.25+134.75)
SA=2(2910.6875)
SA=5821.375
you need enough paint to cover 5821.375 square inches of door
X+y/2=1
-2+6/2=1
-2 + 3 =1 true
⇒ ( -2, 6) is the solution
Answer:
the answer would be B or 358.38
