Answer 4

B. Convert so that Matilda's wall measurements are both in the same units.

D. Add 48 inches and 1.5 yards to obtain the perimeter of Matilda's bedroom.
E. Compare the number of feet of border Matilda bought with the number of feet in the perimeter of her bedroom.

To determine if Matilda bought the correct amount of border, you need to follow these steps:

B. Convert so that Matilda's wall measurements are both in the same units: Since two walls are given in inches and two walls are given in yards, you'll first need to convert the measurements to the same unit. You can either convert the inches to yards or the yards to inches. Let's convert the inches to yards for simplicity.

C. Calculate the number of feet of border that Matilda bought: Since the border cost is given in dollars per foot, you'll need to calculate the length of the border in feet. Multiply the perimeter (which you'll calculate later) by the cost per foot to get the total cost of the border.

D. Add 48 inches and 1.5 yards to obtain the perimeter of Matilda's bedroom: To find the perimeter of Matilda's bedroom, you need to add up the lengths of all four walls. Convert the 48 inches to yards (divide by 36) and add it to the 1.5 yards to get the total perimeter in yards.

E. Compare the number of feet of border Matilda bought with the number of feet in the perimeter of her bedroom: Finally, compare the number of feet of border that Matilda bought (calculated in step C) with the number of feet in the perimeter of her bedroom. If they are the same, then Matilda bought the correct amount of border.
