Given that students shaded the number of squares on the grid listed below.
Hayley, 153 Wade 112, Sanjay, 184 and Eva 155
The person who could have shaded a rectangle that was 5 squares long is Eva with 155 squares.
This is because out of all the listed numbers only 155 is divisible by 5.
Part B:
The number of squares high the shape would be is given by
[tex] \frac{155}{5} =31\, squares[/tex]
