*5.50 per square metre.
​::::::::::::::|:::::::::::::::::

Answer 1

Step-by-step explanation:

Given:

• One side of a square field = 62 m
• Cost of raising lawn for 1 m² = ₹5.50

To find:

• Total cost of raising the lawn = ?

Formula used:

$\boxed{ \sf{area \: of \: square = (Side) {}^{2} }}$

Method:

Area of square = Side²

↦Area = (62)²

→ Area = 62m × 62m

⇒★ Area = 3844 m² ★

Cost of raising lawn for 1 m² = ₹5.50

Cost of raising lawn for 3844 m²

= 3844 × 5.50

= ₹ 21142

Therefore the Total cost of raising lawn = ₹ 21142

Additional information:

• For finding the cost for raising lawn, we need to find area (as in the above answer)
• For finding the cost of raising fence, we need to find perimeter
• Formula used for perimeter of a square is 4 × Side

Answer 2

$\large \tt \pink {answer}$

Area of square = Side²

↦Area = (62)²

→ Area = 62m × 62m

⇒★ Area = 3844 m² ★

Cost of raising lawn for 1 m² = ₹5.50

Cost of raising lawn for 3844 m²

= 3844 × 5.50

= ₹ 21142

Therefore the Total cost of raising lawn = ₹ 21142
