Sample questions

1. What is the area of a rectangle with a length of 5 cm and a width of 3 cm?

   1. 15 cm²
   2. 8 cm²
   3. 10 cm²
   4. 20 cm²
   Show answer

   Answer: A. 15 cm²

   The area of a rectangle is found by multiplying its length by its width. So, 5 cm * 3 cm = 15 cm².

2. What is the area of a triangle with a base of 6 cm and a height of 4 cm?

   1. 12 cm²
   2. 18 cm²
   3. 24 cm²
   4. 20 cm²
   Show answer

   Answer: A. 12 cm²

   The area of a triangle is (base * height) / 2. Thus, (6 cm * 4 cm) / 2 = 12 cm².

3. Find the area of a rhombus with diagonals 8 cm and 6 cm.

   1. 24 cm²
   2. 48 cm²
   3. 36 cm²
   4. 30 cm²
   Show answer

   Answer: A. 24 cm²

   The area of a rhombus is (d1 * d2) / 2. Thus, (8 cm * 6 cm) / 2 = 24 cm².

4. Calculate the area of a trapezoid with bases 3 cm and 5 cm, and height 4 cm.

   1. 16 cm²
   2. 8 cm²
   3. 20 cm²
   4. 14 cm²
   Show answer

   Answer: A. 16 cm²

   The area of a trapezoid is ((b1 + b2) / 2) * height. Thus, ((3 cm + 5 cm) / 2) * 4 cm = 16 cm².

5. What is the area of a regular hexagon with a side of 4 cm?

   1. 41.57 cm²
   2. 48 cm²
   3. 84.64 cm²
   4. 72 cm²
   Show answer

   Answer: A. 41.57 cm²

   Using the formula (3√3/2) * s², where s is the side, area ≈ 41.57 cm² for s = 4 cm.
