Question:

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

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

4 m

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.

4 m

A rectangle has a length of 6p cm and a breadth of 4q cm. Find

4 m
- its area in terms of p and q,
- its perimeter in terms of p and q,
- the area of the rectangle if p = 2 and q = 3.

The figure is made up of a rectangle and a semi-circle. Diameter of the circle is 80 cm. Find the area of the shaded part. (Take π = 3.14)

1 m

The figure shows the net of a cuboid not drawn to scale. Line A (B+H) is 50 cm. Line B (L) is 40 cm Line C (B) is 35 cm. Find the volume of the cuboid.

2 m

The figure is not drawn to scale. It is made up of a square and rectangle. The ratio of the area of the square to that of the rectangle is 1 : 3. After the grey part is cut out, the ratio of the area of unshaded part of the rectangle to that of the square is 5 : 1. Given the length of the square is 5 cm, find the area of the grey part.

2 m
The figure shows a piece of paper. When the shaded rectangles A, C, D and square B is cut out, the remaining parts form the net of a cuboid. Area E is a square. Given that the area of A is 18 cm^{2} and the area of B is 81 cm^{2}, find the volume of the cuboid.

2 m

The figure shows cardboard pieces used to form the net of a cuboid. The area of each square piece is 25 cm^{2} and the area of each rectangular piece is 40cm^{2}

2 m

The figure, not drawn to scale, on the right shows 2 rectangles overlapping each other. The ratio of the shaded area to the area of Rectangle A is 3 : 8. The ratio of the shaded area to the area of Rectangle B is 2 : 5. Find the ratio of the unshaded area to the total area of the figure.

2 m

The figure, not drawn to scale, on the right shows 2 rectangles overlapping each other. The ratio of the shaded area to the area of Rectangle X is 4 : 9. The ratio of the shaded area to the area of Rectangle Y is 3 : 6. Find the ratio of the unshaded area to the total area of the figure.
