Question

plz answer the 2nd question

Answer 1

$1st \: fields \: area = 20 \times b(55) \\ = 1100 \: {m}^{2}$

Area of 2nd field = 40 × D(90)
= 3600 m²

$area \: of \: 3rd \: field = 15 \times a(10) = 150 {m}^{2} \\ \\ \\ area \: of \: 4th \: field = 25 \times c(60) = 1500 {m}^{2}$
Area of 5th field = 24 × E(110) = 2640 m²
