Show answer & explanation
Correct answer: A
Key formula: The area of a rhombus equals half the product of its diagonals.
Area formula:
area = (diagonal₁ × diagonal₂) / 2
Substitute the given diagonals: diagonal₁ = 8 cm and diagonal₂ = 10 cm.
Multiply the diagonals: 8 cm × 10 cm = 80 cm².
Take half of that product: 80 cm² / 2 = 40 cm².
Final answer: 40 cm²
