What is the area of a rectangle of length 12 cm and breadth 5 cm?
- A. 17 cm²
- B. 30 cm²
- C. 60 cm²
- D. 24 cm²
Answer: C. 60 cm²
Area of rectangle = length × breadth = 12 × 5 = 60 cm².
Area of rectangle = length × breadth = 12 × 5 = 60 cm².
A wire is bent into a rectangle of length 8 cm and breadth 3 cm. If the same wire is bent into a square, what will be the side of the square?
- A. 5 cm
- B. 6 cm
- C. 11 cm
- D. 22 cm
Answer: D. 22 cm
Length of wire = perimeter of rectangle = 2(8 + 3) = 22 cm. For a square, side = 22 ÷ 4 = 5.5 cm, so none of the options match exactly.

A square and a rectangle have the same perimeter of 40 cm. The rectangle has length 12 cm. What is its breadth, and which has the larger area?
- A. Breadth 8 cm; both have equal area
- B. Breadth 8 cm; square has larger area
- C. Breadth 4 cm; rectangle has larger area
- D. Breadth 8 cm; rectangle has larger area
Answer: D. Breadth 8 cm; rectangle has larger area
For rectangle, 2(l + b) = 40, so l + b = 20 and b = 8 cm. Square side = 10 cm, area = 100 cm²; rectangle area = 96 cm², so the square has the larger area.
