Answer 1

20 1/6 ft

Explanation:

The perimeter is the sum of the lengths of the sides:

2×(5 1/3 ft) + 2×(4 3/4 ft) = 10 2/3 ft + 8 6/4 ft

= 10 2/3 ft + 9 2/4 ft . . . . change 6/4 ft to 1 1/2 ft

= 10 8/12 ft + 9 6/12 ft = 19 14/12 ft . . . . . use common denominator of 1/12 ft

= 20 2/12 ft . . . . . . change 14/12 ft to 1 2/12 ft; next reduce that fraction

= 20 1/6 ft . . . . perimeter of Caleb's bathroom
