Question

The perimeter of a rhombus is 100cm. Find one of it's sides.

• A. 100 cm
• B. 75 cm
• C. 50 cm
• D. 25 cm

Answer 1

The correct option is D 25 cm

The rhombus is a parallelogram with equal sides.

Perimeter of the rhombus = 100cm
Let, length of one side of the rhombus is a.
Then, a + a+ a+ a = 100 cm
$\Rightarrow$ 4a = 100
$\Rightarrow$ a = $\frac{100}{4}$ = 25
$\Rightarrow$ a = 25cm

Length of sides of the rhombus is 25 cm.
