By answering these questions, I hope you will be able to master the relevant mathematical knowledge and skills. 2. Questions and Answers 1. Question: The length of a rectangle is 12 centimeters and the width is 8 centimeters. Answer: The area of the rectangle = length × width = 12 cm× 8 cm = 96 square centimeters. 2. Question: The side length of a square is 10 cm, find the area of this square? Answer: The area of the square = side length× side length = 10 cm× 10 cm = 100 square centimeters. 311. Question: Knowing that the radius of a circle is 5 cm, find the area of this circle? Answer: The area of the circle = π×r² = 3.14×5² = 78.5 square centimeters. 4. Question: The upper bottom of a trapezoid is 8 cm, the bottom is 12 cm, and the height is 5 cm. Answer: The area of the trapezoid = (upper bottom + lower bottom) × height÷2 = (8 cm + 12 cm) ×5 cm÷2 = 50 square centimeters. 5. Question: Knowing that the base of a triangle is 6 cm and the height is 4 cm, find the area of this triangle? Answer: The area of the triangle = base × height÷2 = 6 cm× 4 cm÷2 = 12 square centimeters. 6. Question: The circumference of a circle is 31.4 cm, find the diameter of this circle? Answer: Diameter of a circle = circumference÷π = 31.4 centimeters ÷ 3.14≈10 centimeters. 7. Question: Twice the number of a number is 78, find this number? Answer: This number = 78÷ 2 = 39. 8. Question: Knowing the equation 3x-2=4, find the value of x? Answer: Solve the equation to get x=(4+2)÷3=2. So the value of x is 2. ​​ Please adjust and expand the above content according to your actual needs, and you can add more types of questions and more detailed analysis processes to meet your needs.
