Question

Jose wants to build a rectangular kennel for his dog. His dad will let him use a spot in the corner of the yard that is 12 feet 3 inches by 8 feet 11 inches. Estimate how much fencing he will need to buy for the kennel.

Answer 1

The answer is 42 ft 4 in

The perimeter of a rectangle with length l and width w is:
P = 2l + 2w

l = 12 ft 3 in
w = 8 ft 11 in

1 ft = 12 in
l = 12 * 12 in + 3 in = 144 in + 3 in = 147 in
w = 8 * 12 in + 11 in = 96 in + 11 in = 107 in

P = 2 * 147 + 2 * 107 = 294 + 214 = 508 in
P = 508 in = 504 in + 4 in = 42 * 12 in + 4 in = 42 ft 4 in

Answer 2

Answer:

42 ft

Step-by-step explanation:

12.3 and 8.11

12.3ft = 147 inches

8.11ft= 107

147+107= 253

253x2=506

506in to ft=42.1667

also im doing this off of an answer I got on my online work so the answers are rounded. so it would be 42 ft rounded.
