Correct Answer - Option 3 : 336

**Given:**

Perimeter of rhombus is 100cm

One diagonal is 48cm

**Formula:**

Area of rhombus = 1/2 × product of diagonals

**Calculations:**

Side of a rhombus,

⇒ 100/4 = 25cm

Diagonals of a rhombus bisect each other,

Half of one diagonal,

⇒48/2 = 24cm

Using Pythagoras theorem,

side^{2} = (half of one diagonal)^{2} + (half of other diagonal)^{2}

Half of other diagonal,

⇒ √625 - 576 = 7 cm

Length of other diagonal,

⇒ 7 × 2 = 14cm

**∴ Area of rhombus = 1/2 × 48 × 14 = 336 cm**^{2}
