K = D. 84
Penjelasan dengan langkah-langkah:
- sisi miring = r
r² = 12² + 35²
= 144 + 1.225
= 1.369
r = √1.369
= 37 m
- K = 35 + 12 + 37
= 84 m
- banyak pohon
= 84 : 2
= 42 pohon
- biaya pohon = 42 x 50.000
= 2.100.000
m² = a² + t²
m² = 35² + 12²
m² = 1.225 + 144
m² = 1.369
m = √1.369
m = 37
K = jumlah semua sisi
K = a + t + m
K = 35 + 12 + 37
K = 47 + 37
K = 84 m
Maka, keliling taman adalah 84 m
