Answer 1

$\huge\red{\fbox{\tt{Aɴѕωєя࿐}}}$

600 m of wire

Step-by-step explanation:

perimeter of sq. = 4 X side

                           = 4 X 50

                           = 200 m

∴ to fence it once, 200 m of wire is required.

∴ to fence it 3 times,

wire needed = 200 X 3

                     = 600 m

$\sf \pmb{ Answer\:=600m}$

Answer 2

Given - Side of square

Find - Cost of fencing

Solution - Cost of fencing the field is Rupees 600.

Perimeter of field = 4*side

Perimeter of field = 4*50

Perimeter of field = 200 metres.

Since fencing has to be done three times, so performing multiplication.

Cost of fencing = 3*200

Cost of fencing = 600

So, cost of fencing the field is Rupees 600.
