Answer 2

Answer:

3 feet 2 inch

63 feet 4 inches

Step-by-step explanation:

1)

1 armrest measuring 1 foot 7 inches

1 foot = 12 inches

1 chair has two armsets

Combined length of two armsets = 1 foot 7 inch +  1 foot 7 inch

= 2 feet + 14 inch

= 2 feet + 12 inch + 2inch

= 2 feet + 1 foot + 2inch

= 3 feet 2 inch

Option C is correct

2) Combined length of 20 chairs arm set

= 20 * ( 3 feet 2 inch)

= 60 feet + 40 inch

= 60 feet + 36 inch + 4 inch

= 60 feet + 3 feet + 4inch

= 63 feet 4 inches

option D is correct
