Painters use surface area to determine how much paint they need to buy. Most homes have 8-foot ceilings. Suppose you're going to paint the walls in one room of the house.
Determine the total surface area of all the walls to be painted. Include the walls in the closets, but ignore windows and doors. Round your answer to the second decimal place. Show all of your calculations and label them appropriately for which room they represent, etc.
The volume of the room is 566 sq ft

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
