Answer 1

Step-by-step explanation:

$lenght \: of \: rectangle \\ \: with \: grass = 95$

$breath \: of \: rectangle \: with \: grass = 70m$

$area \: of \: rectangle \: with \: grass = 95\times 70 = 6650$

$area \: of \: rectangle \: without \: grass = 85 \times 60 = 5100$

$area \: of \: grass \: field = 6650 - 5100 = 1550 \: m {}^{2}$

$10) \: 38 - 10 = 28 \: \: 32 - 10 = 22$

$28 \times 22 = 616m {}^{2}$

$38 \times 32 = 1216$

$area \: of \: path$

$1216 - 616 = 600m {}^{2}$
