Answer 2

Step-by-step explanation:

The ratio between length(l) and breath(b) is 5:3

Let the length be 5x and breath be 3x

$Cost \: of \: 1 \: {m}^{2} = 85 \\ Cost \: to \: cover \: whole \: field = 62475 \\ area \: of \: rectangular \: field = \frac{62475}{85} = 735 \: {m}^{2} \\ \\ area \: of \: rectangle = length \times breath \\ 5x \times 3x = 735 \\ 15 {x}^{2} = 735 \\ {x}^{2} = \frac{735}{15} \\ {x}^{2} = 49 \\ x = \sqrt{49} \\ x = 7 \: m \\ therefore \: \\ length = 5x = 5 \times 7 = 35 \: m \\ breath = 3x = 3 \times 7 = 21 \: m \\ \\ thus \\ perimeter \: of \: the \: rectangle = 2(l + b) = 2(35 + 21) = 2 \times 56 = 112 \: m$
