Question

The length of a rectangular park is three times its breadth. If the perimeter of the park is 192 metres, find the dimensions of the park.

KnowledgeBoat · Accepted Answer

Let the breadth of the rectangular park be x metres. Then, the length of the park = 3x metres. Perimeter of the park = 192 metres We know the formula: Perimeter of a rectangle = 2(Length + Breadth) 192 = 2(3x + x) ⇒ 192 = 6x + 2x ⇒ 192 = 8x ⇒ x = ⇒ x = 24 Breadth = x = 24 m And Length = 3x = 3 × 24 m = 72 m Hence, the dimensions of the park are : Length = 72 m and Breadth = 24 m.
