Another well answered problem! Particularly clear solutions were sent in by James from St Mary's School, Sara-Louise from Perton Middle School and Rowena from Christ Church Infants. Sara-Louise said:My method for this problem was to count the number of squares along one side, then times them by the number of squares along the other side.
Rowena had a slightly different way of finding out the number of squares taken up by each shape. She wrote:I am going to count the whole squares up and across, then draw the outline of the rectangle, and then draw the squares on to it that weren't there before. I will count the squares and put the total into a table.
Here's Rowena's table:
|Rectangle||Number of Squares|
|Orange||3 down x 5 across = 15|
|Blue||4 down x 8 across = 32|
|Green||5 down x 3 across = 15|
|Yellow||5 down by 6 across = 30|
For the final shape, James said:
