no 35 tolong ya kak pakai cara makasih

jawab

ukuran lahan 
a = 20
t = 20
b = 35

ukuran taman
a1= 16

a/t = a1/t1
20/20 = 16/t1
t1 = 16

a/b = a1/b1
20/35 = 16/b1
b1 =  16(35)/20
b1 = 28

Luas jalan = luas lahan - luas taman
L = 1/2 (a +b)t  -  1/2 (a1+b1)t1
L = 1/2 (20+35)(20)  - 1/2 (16 +28)(16)
L  = 10(55) - 8(44)
L = 550 - 352
Luas jalan  = 198 cm²
