Showing 6 of 8 questions
Q1: Find the area of a rectangle with length 8 cm and width 5 cm.
Step 1: Area of rectangle = length × width
Step 2: Area = 8 × 5 = 40 cm²
Q2: Find the area of a triangle with base 12 cm and height 8 cm.
Step 1: Area of triangle = (1/2) × base × height
Step 2: Area = (1/2) × 12 × 8
Step 3: Area = (1/2) × 96 = 48 cm²
Q3: Calculate the circumference and area of a circle with radius 7 cm.
Step 1: Circumference = 2πr = 2 × π × 7 = 14π cm
Step 2: Circumference ≈ 14 × 3.14 = 43.96 cm
Step 3: Area = πr² = π × 7² = 49π cm²
Step 4: Area ≈ 49 × 3.14 = 153.86 cm²
Q4: Find the area of a trapezoid with parallel sides 6 cm and 10 cm, and height 5 cm.
Step 1: Area of trapezoid = (1/2) × (sum of parallel sides) × height
Step 2: Area = (1/2) × (6 + 10) × 5
Step 3: Area = (1/2) × 16 × 5
Step 4: Area = (1/2) × 80 = 40 cm²
Q5: Find the surface area of a cube with side 4 cm.
Step 1: A cube has 6 equal square faces.
Step 2: Area of one face = side² = 4² = 16 cm²
Step 3: Surface area = 6 × 16 = 96 cm²
Q6: Find the volume of a rectangular prism with length 10 cm, width 6 cm, and height 5 cm.
Step 1: Volume = length × width × height
Step 2: Volume = 10 × 6 × 5 = 300 cm³
