Question

How much length of wire is required to fence four rounds around a square garden whose area is 154sq m ?​

Answer 1

hey mate ,

Area of square = side ^2

154 = side ^2

side = √154 cm

Perimeter of square = 4× side

= 4√154

Since they want to fence 4 rounds . Thus perimeter ×4

= 4×4√154

= 16√154 cm

Answer 2

Area = side²

154 = side²

side = 154^1/2

For 4 rounds 4 × perimeter will be required

Perimeter × 4 = 4 × 4 × side

Hence,

(16 × 154^1/2) m of wite will be required.

Or

198.5 m of wire will be required.
