- Q1 of 6Easy
The area of a rectangle is:
Show answerHide answer
Answer: length × breadth
Explanation: Area of a rectangle is the product of its two sides: length × breadth. It is not 2(length + breadth) — that formula finds the perimeter, not the area.
- Q2 of 6Easy
The area of a triangle is:
Show answerHide answer
Answer: ½ × base × height
Explanation: Area of a triangle = ½ × base × height. Skipping the ½ (giving base × height) instead finds the area of a parallelogram with the same base and height.
- Q3 of 6Medium
A trapezium has area 40 cm² and parallel sides 6 cm and 10 cm. Its height is:
Show answerHide answer
Answer: 5 cm
Explanation: ½ × (6 + 10) × h = 40 gives 8 × h = 40, so h = 5 cm. Using only one parallel side instead of their sum would give a different, wrong height.
- Q4 of 6Medium
An L-shaped figure splits into two rectangles of area 20 cm² and 12 cm². Its total area is:
Show answerHide answer
Answer: 32 cm²
Explanation: When a figure splits into non-overlapping rectangles, their areas simply add: 20 + 12 = 32 cm².
- Q5 of 6Hard
A square and a rectangle both have perimeter 24 cm; the rectangle is 8 cm by 4 cm. Which has the larger area?
Show answerHide answer
Answer: the square, 36 cm²
Explanation: A perimeter of 24 cm gives the square a side of 24 ÷ 4 = 6 cm and area 6 × 6 = 36 cm², beating the rectangle's 8 × 4 = 32 cm² — for a fixed perimeter, a square encloses the most area.
- Q6 of 6Hard
A parallelogram and a triangle share base 8 cm and height 6 cm. The parallelogram's area exceeds the triangle's by:
Show answerHide answer
Answer: 24 cm²
Explanation: Parallelogram area = 8 × 6 = 48 cm², triangle area = ½ × 8 × 6 = 24 cm² — same base and height, so the parallelogram is exactly double, a difference of 24 cm².
Area notes: key concepts (Class 8 Mathematics)
This chapter measures the space inside flat shapes. Area is counted in square units, and each shape has its own formula: a rectangle is length × breadth, a square is side², a triangle is half base × height, and a parallelogram is base × height. A trapezium uses half the sum of its parallel sides times the height, and a rhombus uses half the product of its diagonals. You also find areas of composite figures by splitting or subtracting, and apply all this to tiling, painting and field problems.
- Area
- The amount of surface a flat shape covers, measured in square units such as cm² or m²; it is different from perimeter, which is the distance around the shape.
- Area of a rectangle
- Length × breadth. A 5 cm by 3 cm rectangle covers 15 cm²; swapping length and breadth does not change the area.
- Area of a square
- Side × side = side². A square of side 7 cm has area 49 cm², and from a known area the side is the square root of it.
- Area of a triangle
- ½ × base × height, where the height is measured perpendicular to the chosen base. A base of 10 cm and height 8 cm gives 40 cm².
- Base and height
- The height must be the perpendicular distance from the base to the opposite vertex (or side), not a slanting length.
- Area of a parallelogram
- Base × height. A parallelogram and a rectangle with the same base and height have the same area.
- Area of a trapezium
- ½ × (sum of the two parallel sides) × height; add the parallel sides first, then halve and multiply by the height.
- Area of a rhombus
- ½ × (product of the diagonals), since the diagonals cut the rhombus into four right triangles.
- Composite figures
- Find the area of an irregular shape by splitting it into rectangles and triangles and adding, or by subtracting a cut-out from a larger shape.
- Area versus perimeter
- Perimeter is the distance around a shape (ordinary units); area is the space inside it (square units) — two different measures.
- Scaling and area
- When every length of a figure is multiplied by a factor k, its area is multiplied by k², so doubling the sides makes the area 4 times as big.
