88 square feet is answerrrrrrrrrrrrrrr

Answer:

Option D. 384 square feet.

Step-by-step explanation:

Nancy is going to do some painting in her room.

The length of room = 13 feet

the width of room = 11 feet.

The room has 4 walls of 2 (11 feet) and 2 (13 feet) and the height of the wall is 8 feet.

The total area of the walls = 2( 11 × 8 + 13 × 8 )

= 2 ( 88 + 104 ) = 2 × 384 = 384 square feet

Nancy would paint total 384 square feet.
