Please help and thank you! Will mark whoever answers right the brainliest! John will paint the walls and ceiling of the room shown. The windows measures 3 feet by 6 feet. The door measures 7 feet by 3 feet.
Part A: Describe the surfaces John will not paint.
Part B: Judy says you need to use subtraction to find the area of the surfaces John will paint. Is Judy correct? Explain.
Part C: A gallon of paint covers about 350 squared feet. How many gallons of paint will John need to buy to paint the walls and ceiling of the room? Justify your answer.

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)

52 gallons because, he will.

And I think Judy is wrong because you need to multiply the thingys, then once you have them, you divide, then that number you take it and subtract by what you have, then you get that many more, then  you do something.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
