Question

5.
The thickness of each book is 39 mm and each book stand is 5.5 cm wide. A
bookshelf holds 45 books and two book stands. How long (measured in m) is the
bookshelf?

Answer 1

Answer:

1.865 m

Step-by-step explanation:

(45 x 39 mm) + (2 x 5.5 cm)

1755 mm + 11 cm

1,755 mm = 1.755 m and 11 cm = 0.11 m

1.755 m + 0.11 m = 1.865 m
