To determine how many square inches of Julie's door will be covered by the pictures, we need to follow a series of steps:
1. Calculate the area of one picture:
Each picture measures 4 inches in width and 6 inches in height. The area of a rectangle is found by multiplying its width by its height.
[tex]\[
\text{Area of one picture} = \text{width} \times \text{height} = 4 \text{ inches} \times 6 \text{ inches} = 24 \text{ square inches}
\][/tex]
2. Calculate the total area covered by all the pictures:
Julie has a total of 5 pictures. The total area covered by these pictures is found by multiplying the area of one picture by the number of pictures.
[tex]\[
\text{Total area covered} = \text{area of one picture} \times \text{number of pictures} = 24 \text{ square inches} \times 5 = 120 \text{ square inches}
\][/tex]
So, the total area covered by the pictures on Julie's door is 120 square inches. Therefore, the correct answer is:
OB. 120 square inches
