Has consistently make reference to the given information and conditions when describing how to arrive at the area representing the cut-out. The explanation is clear and systematic.

You listed the factors of 20 to help deduce the pair of factors that gives rise to the area 20 in the following manner: 20: 1, 2, 4, 5, 10, 20. It would be more appropriate by listing the factors in "pairs", rather then just listing them all in a line.

The conversion of unit: You mentioned 1 m^2 = 100 cm x 1 cm which should be 100 cm x 100 cm

m^2 should be read as "square metre"
