For Monica 14th birthday she wants to make over her bedroom the first phase in the bedroom makeover is painting her room if monica’s room is 20 ft long 15 paint including the floor and ceiling

The total square footage of Monica's room is 20 ft x 15 ft = 300 square feet.

Since she wants to paint the walls, floor, and ceiling, we need to calculate the total square footage to be painted.

The walls will have a total square footage of 2 * (20 ft + 15 ft) * 8 ft (assuming a standard wall height) = 2 * 35 ft * 8 ft = 560 square feet.

The floor will have a square footage of 20 ft x 15 ft = 300 square feet.

The ceiling will have a square footage of 20 ft x 15 ft = 300 square feet.

So, the total square footage to be painted is 560 sq ft (walls) + 300 sq ft (floor) + 300 sq ft (ceiling) = 1160 square feet.

Monica will need 1160 sq ft of paint for her bedroom makeover.
