Level 3
Each figure is made up of a number of identical sticks of 1-cm length.

1. Find the perimeter of Figure 50.
2. Find the number of sticks in Figure 100.
3. Given that a figure has a perimeter, P, of 254 cm, find the number of squares in this figure.

Level 3
The area of the triangle to the area of the rectangle in the figure is in the ratio 3 : 2. After the shaded rectangle of length 8 cm is removed from the figure, the ratio of the remaining area of the triangle to the remaining area of the rectangle is 5 : 3. Given that the area of the triangle is 32 cm² more than the area of the rectangle, find the width of the shaded rectangle that is being removed.

Level 3
The figure shows 2 rectangles. The length of the bigger rectangle is (6m + 8) cm and the breadth is half its length. Find the perimeter of the smaller rectangle.

Level 3
The perimeter of triangle A is equal to that of rectangle B.

1. Find the length of rectangle B in terms of k.
2. If k = 3, find the area of rectangle B.
