Study the diagram. Answer the following.
- What is the length of the pin?
- How much longer is the chalk than the pin?
- The total length of the pin, the chalk and the comb?
(a)
Length of the pin
= 20 - 18
= 2 cm
(b)
Length of the chalk
= 21 - 17
= 4 cm
Difference in the length between the chalk and the pin
= 4 - 2
= 2 cm
(c)
Length of the comb
= 22 - 16
= 6 cm
Total length of the pin, chalk and the comb
= 2 + 4 + 6
= 12 cm
Answer(s): (a) 2 cm; (b) 2 cm; (c) 12 cm
