CTET Paper I (Classes I to V) 28 Jan 2023 Solved Paper

Concept:Area formulas for rectangle, square, circle, and right-angled triangle are compared to find the largest area.Explanation:First, compute area of rectangle: $3 \times 4 = 12$ square units.Next, area of square: $3^2 = 9$ square units.Then, area of circle: $\pi \times 2^2 = 4\pi \approx 12.57$ square units.Finally, area of right triangle: $\frac{1}{2} \times 3 \times 4 = 6$ square units.Compare the results: $12.57 > 12 > 9 > 6$. So the circle has the largest area.Answer:Option C: Circle with radius 2 units.
