Question

8. The cost of putting a fence around a square field at 45 per metre is 5760. Find the length of each side of the field.​

Answer 1

♣GIVEN♣

• Rate of fencing around the square field = ₹45/m

• Cost of fencing around the field = ₹ 5670

♣TO FIND♣

• Length of each side of the square field

♣SOLUTION♣

➊ First let us find the perimeter of the square field :-

• Perimeter = (Cost of fencing/Rate of fencing) m

→ Perimeter = (5760/45) m

→ Perimeter = (128/1) m

→ Perimeter = 128 m

➋ Now let us find the length of each side of the square field :-

• Length of each side of square field = (Perimeter/4) m

→ Length of each side of the field = (128/4) m

→ Length of each side of the field = (32/1) m

→ Length of each side of the field = 32 m

♣ANSWER♣

• Length of each side of the field is 32 m
