1. What is the formula for the area of a rectangle?
Correct Answer: B
Area of rectangle = length × breadth. It measures the surface covered by the rectangle.
Area of rectangle = length × breadth. It measures the surface covered by the rectangle.
2. Find the area of a rectangle with length 12 cm and breadth 5 cm.
Correct Answer: A
Area = 12 × 5 = 60 cm².
Area = 12 × 5 = 60 cm².
3. What is the formula for the area of a triangle?
Correct Answer: B
Area of triangle = ½ × base × height. Height must be perpendicular to the base.
Area of triangle = ½ × base × height. Height must be perpendicular to the base.
4. Find the area of a triangle with base 10 cm and height 8 cm.
Correct Answer: B
Area = ½ × 10 × 8 = 40 cm².
Area = ½ × 10 × 8 = 40 cm².
5. The area of a parallelogram is:
Correct Answer: B
Area of parallelogram = base × height (perpendicular height).
Area of parallelogram = base × height (perpendicular height).
6. Base = 15 cm, height = 6 cm. Area of parallelogram?
Correct Answer: A
Area = 15 × 6 = 90 cm².
Area = 15 × 6 = 90 cm².
7. If a rectangle has area 48 cm² and breadth 6 cm, its length is:
Correct Answer: B
Length = Area ÷ Breadth = 48 ÷ 6 = 8 cm.
Length = Area ÷ Breadth = 48 ÷ 6 = 8 cm.
8. Area of triangle becomes zero when:
Correct Answer: C
If base or height is zero, area becomes zero.
If base or height is zero, area becomes zero.
9. Area of square with side 9 cm:
Correct Answer: B
Area = side² = 9² = 81 cm².
Area = side² = 9² = 81 cm².
10. A triangle has area 35 cm² and base 7 cm. Height is:
Correct Answer: B
35 = ½ × 7 × h ⇒ h = 10 cm.
35 = ½ × 7 × h ⇒ h = 10 cm.
11. Area of rectangle equals area of parallelogram when:
Correct Answer: A
Both formulas are base × height.
Both formulas are base × height.
12. Area of triangle with base 14 cm and height 5 cm:
Correct Answer: A
Area = ½ × 14 × 5 = 35 cm².
Area = ½ × 14 × 5 = 35 cm².
20. Base of parallelogram is 20 cm and height 12 cm. Area is:
Correct Answer: A
Area = base × height = 20 × 12 = 240 cm².
Area = base × height = 20 × 12 = 240 cm².
