Answer: E. I, II, and III Question 4: Step 1: The area of a small square is 9 square cm. Then, the side of a small square is sqrt(9) = 3 cm. Thus, the length and width of the rectangle are 3 * 3 = 9 cm and 2 * 3 = 6 cm, respectively. Step 2: Then, the perimeter of the rectangle is- 2(9 + 6) = 2 * 15 = 30 cm. Answer: B. 30 cm Question 5: Step 1: A triangular prism has 3 rectangular and two triangular faces. Step 2: So, the total number of faces that a triangular prism has is 3 + 2 = 5 faces. Answer: C. 5 faces Question 6: Step 1: For quadrilateral A (parallelogram), the base is 3 and the corresponding height is 2. So, its area is 2 * 3 = 6 square units. For quadrilateral B (trapezium), the lengths of parallel sides are 2 and 4 and the height is 2. So, its area is 1/2 * (2 + 4) * 2 = 6 square units. Step 2: For quadrilateral C (rectangle), the length is 7 and the width is 1. So, its area is 7 * 1 = 7 square units. ©Scholarly 2025. All rights reserved.

Step 1: The width of the living room is 20 - 8 = 12 metres. The length of the living room is 18 - 4 = 14 metres. Step 2: Then, the perimeter of the living room is - P = 2(12 + 14) = 52 metres. Answer: D. 52 metres Question 10: Step 1: The dimensions of the first face are 4 * 2. The dimensions of the second face are 6 * 4. And, the dimensions of the third face are 6 * 2. So, the length, width, and height of the prism are 6, 4, and 2 units, respectively. Step 2: Then, the volume of the prism is 6 * 4 * 2 = 48 cubic units. So, the prism is made up of 48 small cubes. Answer: B. 48 cubes Question 11: Step 1: The area of the folded figure is 16 square metres. The area after the first unfold is 16 * 2 = 32 square metres. Step 2: The area after the second unfold is 32 * 2 = 64 square metres. So, the area of the original unfolded paper was 64 square metres. ©Scholarly 2025. All rights reserved.
