The diagram shows 3 squares, the length of which are 1 cm, 2 cm and 3 cm respectively. Each square is made up of small squares which has a length of 1 cm and alternate squares are coloured grey and white.
How many small grey squares are needed to create a square of side 11 cm?
Find the length of the side of a square if 196 small grey and white squares are used to create it.
Find the number of small white squares when a square of side 18 cm is created?

Level 3
The figure shows an irregular 5-sided figure and a square. The area of the five-sided figure was three times the area of the square. After the shaded part was removed, the area of the remaining square became 15% of the total remaining area of both figures. If the area of the shaded part is 16 cm2, find the remaining area of the 5-sided figure.

Level 3
1-cm square tiles and triangular tiles were used to make some figures. The area of each triangular tile was half that of a square tile. The first four figures are shown.
Find the area of Figure 5.
How many squares were used to make a figure with an area of
