Question

lometres. A rectangular garden has its length and breadth in the ratio 4: 3. Its area is 7.68 hectares. Find its Perimeter.​

Answer 1

Answer:

Let the length be 4x

let the breadth be 3x

1 hectare = 10000m²

7.68 hectare = 76800m²

Area of rectangular garden = l×b

76800 = 4x × 5x

76800 = 20x²

x² = 3840

x = 62 m (approx)

Therefore,

Length = 248 m

Breadth = 186 m

Perimeter = 4(l+b)

= 4(434)

= 1736 m
