The diagonals of a rhombus have lengths 16 cm and 12 cm. What is the side length of the rhombus?
Show answer & explanation
Correct answer: B
Explanation
Given:
Diagonal₁ = 16 cm
Diagonal₂ = 12 cm
According to the formula:
Side of a rhombus = √[(d₁/2)² + (d₂/2)²]
d₁/2 = 16/2 = 8
d₂/2 = 12/2 = 6
Side = √(8² + 6²)
= √(64 + 36)
= √100
= 10 cm
