The perimeter of a rectangular field is 3/5 km and its length is twice breadth. Find the area of the field in m2.

Question

KnowledgeBoat · Accepted Answer

Let length = l and breadth = b Given, Perimeter = l = 2b By formula, Perimeter = 2(l + b) ⇒ = 2(2b + b) ⇒ = 3b ⇒ 3b = 300 ⇒ b = 100 m. ⇒ l = 2b = 2 × 100 = 200 m. Area = l × b = 200 × 100 = 20000 m2. Hence, area of the field = 20000 m2.
