Question

Area of a rhombus is 360 cm². If one diagonal of it is 20 cm; the other diagonal is ______.

Options

• 24 cm

• 18 cm

• 40 cm

• 36 cm

Answer 1

Area of a rhombus is 360 cm². If one diagonal of it is 20 cm; the other diagonal is 36 cm.

Explanation:

The area of a rhombus is given by \[\frac{1}{2} \times d_1 \times d_2\]. Substituting the known values gives \[360 = \frac{1}{2} \times 20 \times d_2\], which simplifies to \[360 = 10 \times d_2\], resulting in \[d_2 = 36\text{ cm}\].
