Question

If the lengths of two diagonals of a rhombus are 12 cm and 16 cm, then the length of each side of the rhombus is

• A. $10$ cm
• B. $14$ cm
• C. cannot be determined
• D. none ofthese

Answer 1

The correct option is A $10$ cm

Length of the each side of a rhombus
$\sqrt{{\left(\frac{d_1}{2}\right)}^2+{\left(\frac{d_2}{2}\right)}^2}$
$\sqrt{{\left(\frac{12}{2}\right)}^2+{\left(\frac{16}{2}\right)}^2}$
$\sqrt{6^2+8^2}$
$\sqrt{100}$
$10cm$
