Question
Measure the side of the red square on the dotted sheet. Draw here as many rectangles as possible using 12 such squares.
How many rectangles could you make?
Solution
The side of the square is 1 centimetre.
The following figure shows the possible rectangles using 12 such squares.
There are 7 rectangles.
- 2 rectangles are of size 1 × 12 centimetres.
- 1 rectangle is of size 2 × 6 centimetres.
- 4 rectangles are of size 3 × 4 centimetre
Hence, number of rectangles
