Question

Convert the following measurements. a. 13 miles to yards b. 67 square feet to square inches c. 4,800 inches to feet d. 87,120 square yards to acres e. 3 miles to yards f. 54 inches to yards g. 12 yards to feet h. 7 acres to square feet

Answer 1

a. 13 miles to yards

1 mile is equal to 1,760 yards, then 13 mi= 13×1,760 yd=22,880 yd.

b. 67 square feet to square inches1 feet is equal to 12 inches and 1 square feet is rqual to 144 square inches, then 67 sq. ft.=67×144 sq. in.=9,648 sq. in.

c. 4,800 in=(4,800÷12) ft.=400 ft.

d. 87,120 square yards to acres
1 Square yard = 0.00020661157 acre, then 87,120 sq. yd.=87,120×0.00020661157 acres=17.9999999784 acres

e. 3 mi=3×1,760 yd=5,280 yd.
f. 54 inches to yards54 in=(48+4) in.=(48÷12)ft 4 in.=4 ft. 4 in.=(3+1) ft. 4 in.=1 yd. 1 ft. 4 in.1 feet is equal to 12 inches and 1 yard is equal to 3 feets

g. 12 yards to feet1 yard is equal to 3 feets, then 12 yd.=12×3 ft.=36 ft.

h. 7 acres to square feet1 acre = 43,560 square feet, then 7 acres=43,560×7 sq. ft.=304,920 sq. ft.

Answer 2

dddFor this case we have to know the following conversions:
1 mile = 1760 yards
1 foot = 12 inches
1 acre = 4840 yd ^ 2
1 yard = 36 inches
1 yard = 3 feet
1 acre = 43560 ft ^ 2
Applying conversions we have:

13 miles to yards:
(13) * (1760) = 22880 yards

67 square feet to square inches:
(67) * (12) ^ 2 = 9648 in ^ 2

4,800 inches to feet:
(4800) * (1/12) = 400 feet

87,120 square yards to acres:
(87120) * (1/4840) = 18 acres

3 miles to yards:
(3) * (1760) = 5280 yards

54 inches to yards:
(54) * (1/36) = 1.5 yards

12 yards to feet:
(12) * (3) = 36 feet

7 acres to square feet:
(7) * (43560) = 304920 feet ^ 2
