Question

The length and breadth of a rectangular field are 22.5m and 14.5 m respectively . find the cost of fencing its four sides at the rate if RS 12 per metre

Answer 1

$length = 22.5 \\ breadth = 14.5 \\ \\ total \: fencing \: length = 2(length + breadth) \\ = 2(22.5 + 14.5) \\ = 2 \times 37 \\ = 74 \: cm \\ the \: cost \: offencing \: per \: rs \: 12 = 74 \times 12 \\ = rs.788$

Answer 2

$\huge\green{\mathfrak{Bonjour!!}}$

$\blue{\textbf{Perimeter=2(l+b)}}$

$\blue{\textbf{Perimeter=2(22.5+14.5)}}$

$\blue{\textbf{Perimeter=2(37)}}$

$\blue{\textbf{Perimeter=74m}}$

$\blue{\textbf{Cost\:of\:Fencing:}}$

$\blue{\boxed{\textbf{RS888}}}$
