Question

The area of a square field is 296 m². find the
cost of fencing the field at the rate of Rs 20 per meter​

Answer 1

GIVEN THAT

• Area of square field = 296 m²

Cost of fencing field per metre = Rs 20

TO FIND

• Total cost of fencing of the field

FORMULA USED

• Area of square = (side)²
• Perimeter of square = 4 × side

SOLUTION

• Area of square field = 256 m²

➡️ (Side)² = 256

➡️ Side = √256

➡️ Side = 16

• So, side of the square field is 16 m

NOW,

• Perimeter of square field = 4 × side

➡️ (16 × 4)m

➡️ 64 m

Total cost of fencing the square field

= Rs(64 × 20) = Rs 1280

Answer 2

Step-by-step explanation:

area of squre = side x side

296= side x side

√296=16

perimeter of square= 4 x side

=4 x 16=64

cost of facing the field=20 x 64

=1280 Rs
