Tolong jawab no.39 dengan cara ya

a. luas lahan tanaman apotek hidup di kelurahan Togogan
= 100 - (22 + 6 + 22 + 22 + 17)
= 100 - 89 = 11% (temulawak)
= 11/100 x a = 220 are
= a = 220 : 11/100
= a = 220 x 100 / 11
= a = 22.000 / 11
= a = 2000 are = 20 hektare

b. luas lahan jahe di kelurahan Togogan
= 17 / 100 x 20
= 340 / 100
= 34 / 10
= 3.4 hektare
