Julie printed out a picture of each of the four members of her favorite band to decorate her bedroom door. Each picture measures 8 inches by 10 inches. Once decorated, how many square inches of Julie's door will be covered by these pictures?
A.
144 square inches
B.
320 square inches
C.
400 square inches
D.
240 square inches
D. 320 square inches
Calculations:
Each picture measures 8 inches by 10 inches.
Area of one picture = 8 inches * 10 inches = 80 square inches
Julie has four pictures, so the total area covered by the pictures is:
80 square inches/picture * 4 pictures = 320 square inches.
