**Given:**

The semi-perimeter of the rectangle is 32 cm

Length ∶ Breadth = 9 ∶ 7

**Formula used:**

Semi-perimeter of rectangle = (l + b)

Area of the rectangle = l × b

**Explanation:**

Let length & breadth of the rectangle be 9x & 7x respectively.

Semi-perimeter of rectangle = (l + b)

⇒ (l + b) = 32

⇒ (9x + 7x) = 32

⇒ x = 2

Area of the rectangle = l × b

⇒ (9x) × (7x)

⇒ 63x^{2}

⇒ 252 cm^{2}

**∴ The area of the rectangle is 252 cm ^{2}.**
