|
Answer» Step-by-step explanation:LET the breadth of the RECTANGULAR plot be x.∴ Length of the rectangular plot = 2xPerimeter of the rectangular plot = 300 mFormula of perimeter = 2(l+b)⇒ 300 = 2 (2x + x)⇒ 300 = 2 × 3x⇒ 300 = 6x⇒ 300/6 = x⇒ x = 50∴ Breadth = 50m Length = 2x = 2 × 50m = 100mArea of the rectangular plot = l × b = 100 × 50 = 5,000 m²∴ Area of the rectangular plot = 5,000 m²Hope that HELPS you.☺ |
