Exercise 8c
Measuring a fence is slightly different because
there are spaces between the strips of wood.
(We won't worry about the fact that there will be an extra space
at one end of the fence and a post at each end.)
A fence has 64 strips of wood. Each strip is 8cm wide. The strips are 7cm apart.
Question: How long is the fence?
Answer: | 640cm | 1020cm | 960cm |
