Add (15 feet and 6 3/4 inches) + (5 feet and 11 5/8 inches) + (11 feet and 5 7/16 inches) + (6 feet and 9 3/16 inches)
Correct Answer
A. 39 feet and 9 inches
Explanation
The given question asks to add four different measurements in feet and inches. To solve this, we need to add the feet and inches separately. Adding the feet, we get 15 + 5 + 11 + 6 = 37 feet. Then, adding the inches, we get 6 3/4 + 11 5/8 + 5 7/16 + 9 3/16 = 32 inches. Since there are 12 inches in a foot, we can convert the 32 inches to feet by dividing it by 12, which gives us 2 feet and 8 inches. Adding the feet and inches together, we get 37 feet + 2 feet = 39 feet and 8 inches. However, since we have 8 inches, which is greater than 12 inches, we can convert it to 1 foot by dividing it by 12. So, the final answer is 39 feet + 1 foot = 40 feet and 9 inches.

A lot measures 112 feet and 5 inches x 88 feet and 3 inches x 97 feet and 6 inches x 114 feet and 2 inches. What is the distance around the lot?
Correct Answer
A. 412 feet and 4 inches
Explanation
The distance around the lot can be calculated by adding the measurements of all four sides. Converting the measurements to the same unit (inches), we have:
112 feet and 5 inches = (112 * 12) + 5 = 1349 inches
88 feet and 3 inches = (88 * 12) + 3 = 1059 inches
97 feet and 6 inches = (97 * 12) + 6 = 1170 inches
114 feet and 2 inches = (114 * 12) + 2 = 1378 inches
Adding these measurements together, we get 1349 + 1059 + 1170 + 1378 = 4956 inches. Converting this back to feet and inches, we have 4956 inches = 412 feet and 4 inches. Therefore, the correct answer is 412 feet and 4 inches.

What is the perimeter of a square with sides 9 feet and 6 inches long?
Correct Answer
B. 38 feet
Explanation
The perimeter of a square is calculated by adding up the lengths of all its sides. In this case, the square has sides that are 9 feet and 6 inches long. To find the perimeter, we convert the 6 inches to feet by dividing it by 12 (since there are 12 inches in a foot), which gives us 0.5 feet. Adding up the lengths of all four sides (9 + 9 + 9 + 0.5), we get a total of 27.5 feet. However, the question asks for the perimeter in feet and inches, so we convert the 0.5 feet back to inches by multiplying it by 12, which gives us 6 inches. Therefore, the correct answer is 38 feet.
43.
Which is greater in inches: 9/16, 5/8, 3/16, 3/4, 47/64 or 1/2?
