Question

calculate the perimeter of a rectangle whose length is 15 and 12 respectively .find the cost of fencing the field at the rate of 25 per metre.​

Answer 1

$\sf \: Length = 15m \\ \sf \: Breadth = 12m$

$\sf \: Perimeter = 2(l + b) \\ = 2(15 + 12) \\ \sf \boxed { \sf \: Perimeter = 54 \: m}$

$\sf \: Cost \: of \: fencing \: will \: be =$

$\sf \: Cost \: of \: \\ \sf fencing \: will \: be = Perimeter \times 25 \\ = 54 \times 25 \\ = 1350 \\ \boxed{\boxed{ \sf Cost = ₹1350}}$
