Length = 20 (cm) Width = 4 (cm)

Answer space takes precedence.
Must be in the correct order for B2.
Award B1 for one of the following as a final answer or final attempt:

length × width = 80
(e.g. length = 4 AND width = 20 or
length = 16 AND width = 5)
80 ÷ width = length
e.g 80 ÷ 5 = 16 or 80 ÷ 20 = 4 or 80 ÷ 10 = 8
length = 5 × width
e.g length = 16 AND width = 3·2 or 3 × 5 = 15

If no answers are given on answer space:

Length = 20 (cm) and Width = 4 (cm) must be explicitly identified as a final answer for B2.
