Confused about velocity-time graph QUESTION

Hi
unsure how to calculate one square of this graph for a curve.
help needed
Mark scheme
Evidence of determining the area under the graph 1 square is equivalent to 2.5 × 10−4 (m) OR 9 to 11 squares 2.3 × 10−3 to 2.7 × 10−3 (m)

2 squares on vertical axis represent 0.1 ms-1
so 1 square on vertical axis represents 0.05 ms-1

2 squares on horizontal axis represent 1 x 10^-2 s
1 square on horizontal axis represents 0.5 x 10^-2 s

so area of 1 square represents = 0.5 x 10^-2 x 0.05 = 2.5 x 10^-4 m

the required area is 2.5 x 10^-3 m (10 squares)

Thank you! A lot more clearer now
