Answer 2

Step-by-step explanation:

Let length and breadth be x

Area or Rectangle = 1 hectare 3500 square meter

= 13,500 square meter

Then , Area = 5x × 3x

13,500 = 5x × 3x

13,500 = 15x^2

13,500 ÷ 15 = x^2

900 = x^2

$\sqrt{900 = x}$

30 = x

Then length will be = 5 × 30 = 150

breadth will be = 3 × 30 = 90

Length = 150 square hectare

breath = 90 square hectare

Perimeter of rectangle = 2(l+b)

= 2(150 + 90)

= 2(240)

= 480 square hectare

Perimeter of rectangle = 480 square hectare
