Answer 1

★ Given :

The cost of fencing around a square field is RS 12000. If cost of fencing per metre is RS 20.

★ To find :

Perimeter of Square field

★ Solution :

✦ Cost of fencing Per Metre= Rs 20

✦ Total cost of fencing = Rs 12000

⚘ So, The length of fencing (Perimeter)

➞ Total cost/cost per metre

➞ 12000/20

➞ 600 m

⚘Length = Perimeter of field

➞ 4 × side of the field = 600

➞ Side of the field = 600/4

➞ 150 m

⚘ Perimeter of the field = 4 × side

➞ 4 × 150

➞ 600 m

Perimeter of square field is 600 m.
