The area of a kite is 51.68 square inches. One diagonal measures 15.2 inches. What is the measure of the other diagonal?

The area of a kite is half the product of its diagonals: A = (d₁ × d₂) ÷ 2. Solving for the other diagonal gives d₂ = (2 × 51.68) ÷ 15.2 = 103.36 ÷ 15.2 = 6.8 inches. The correct choice is 6.8 inches.
