Question

The dog park is 13 mile wide and 12 mile long. Shayna walks her dog, Buster, around the perimeter of the dog park two times.

Do Shayna and Buster walk more or less than 3 miles?

Answer 1

PERIMETER = 1/3 + 1/3 + 1/2 + 1/2 = 2/3 + 1 = 1 2/3 miles for 1 LAP.

For 2 LAPS, 2 x 1 2/3 = (2 x 1) + 2(2/3) = 2 + 4/3 = 2 + 1 1/3 = 3 1/3 miles

Or, 2 x 1 2/3 = 6/3 x 5/3 = 30/9 = 3 3/9 = 3 1/3 miles

Or, 2/1 x 5/3 = 10/3 = 3 1/3 miles

ANSWER: MORE THAN 3 MILES
