Answer:

71 1/2 square feet

Step-by-step explanation:

We want to find the area of the wall that will be painted.

We need to find the area of the two windows and subtract it from the area of the wall.

Each window is 3 1 /2 ft by 4 1/2 ft. The area of each window is therefore:

A = L * B

A = 7/2 * 9/2 =  = 63/4 square feet = 15 3/4 square feet

The two windows therefore have an area of:

2 * 63/4 = 63/2 = 31 1/2 square feet.

The wall measures 12 7/8 ft by 8 ft. Therefore, the area of the wall is:

A = 103/8 * 8 = 103 square feet

The area of the wall that will be painted is therefore:

A = 103 - 31 1/2 = 71 1/2 square feet

The total number of beads that Lexi could accommodate based on the on hand items is 101 beads. Subtract the number of beads she needs which is 144 beads with 101 beads. The amount of beads that would need a box is 43 beads. Since a medium box could only accommodate 10 beads at a time, divide 43 with 10 and the answer would be 4 remainder 3. Thus Lexi would only need 4 medium boxes.
