    Answer: 34 cm

    Perimeter = 2 × (length + width) = 2 × (12 + 5) = 2 × 17 = 34 cm.

  3. A circle has a radius of 7 cm. What is its area? (Use π ≈ 22/7)

    Answer: 154 cm²

    Area = π × r² = (22/7) × 7² = (22/7) × 49 = 154 cm².

    Answer: All sides are equal

    An equilateral triangle has all three sides equal and all three angles equal to 60°.

  5. What is the area of a triangle with base 10 cm and height 6 cm?

    Answer: 30 cm²

    Area of a triangle = (1/2) × base × height = (1/2) × 10 × 6 = 30 cm².
