Question

Find the perimeter and area of square field of side 12cm.Also find the cost of levelling the field at the rate of ₹15/cm²

Answer 1

Given

$\bold{Length\ of \ one \ side \ of \ the \ square} = 12 \ cm$

SOMETHING YOU NEED TO KNOW

$\sf \bold{Area \ of \ a \ square} = side * side$

$\sf \bold{Perimeter \ of \ a \ square} = 4 \times side$

$\implies \sf Area \ of \ the \ square$

$= 12 \times 12$

$= \boxed{\boxed{\bold{ 144 \ cm^{2}}}}}}}}}$

$\implies \sf Perimeter \ of \ the \ square$

$= 4 \times 12$

$= \boxed{\boxed{\bold{48 \ cm}}}}}$

$\sf Cost \ of \ leveling \ the \ field$

$= 15 \times 48$

$= \boxed{\boxed{\bold{ 720 \ Rupees}}}}}}}$

                                                         

Answer 2

Given :-

• Length of one side of the square = 12 cm.

To find :-

• Area of square field
• Perimeter of square field
• Cost of leveling the field

Formula used :-

• Area of square = side × side
• Perimeter of a square = 4 × side

According to the question,

Area of square = 12 cm × 12 cm

= 144 cm²

Perimeter of square = 4 × 12 cm

= 48 cm

Cost of leveling the square field = ₹ 15 × 48

= ₹ 720.
