Have a look below at 5HC's amazing reasoning with area. They worked out that in order to solve the problem they needed to find the area of the different squares.

For example a square with 4cm sides would have an area of 16cm2.

After that they worked out the area that the rectangle would be and then put some squares together to find possible lengths of the side of the rectangle. They knew they had to be able to divide the total area by the length of a side exactly, and checked that.

Oliver said "When we put the 15x15 square next to the 18x18 square we got a length of 33cm and found this was a factor of the total area and that the other side had to be 32 cm, so we rearranged the squares until we had made that rectangle"
