B. 42-√3-2/3 feet
C. 12/3+1/₃ feet
D. 21⅓ - √2 feet

Answer 1

Austin needs to buy 18 feet of border for his bathroom wall.

Step-by-step explanation:

To find the amount of border Austin needs to buy, we need to calculate the perimeter of the wall.

The length of the wall is 15/3 - 4₂ feet, and the height is 3 - 2 + 6₃ feet.

To calculate the perimeter, we add together the lengths of all four sides.

Let's start with the length. 15/3 can be simplified to 5, and when we subtract 4₂ from that, we get 2.

For the height, 3-2+6₃ simplifies to 7.

Adding up the four sides, we get 2+2+7+7 which equals 18 feet.

So, Austin needs to buy 18 feet of border.
