pake cara phytagoras untuk cari sisi BC dan AB
BC²= √BE² + EC²
= √8² + 6²
= √64 + 36
= √100
BC = 10 m
AB² = √AE² + BE²
= √15² + 8²
= √225 + 64
=√289
AB = 17
Kll layang² = 2 x (sisi BC + sisi AB)
= 2 x (10 + 17)
= 2 x 27
= 54 m
karena tanaman diberi jarak 2 m maka..
54 m : 2 m = 27 buah tanaman
1 tanaman = Rp. 25.000
27 tanaman = Rp. 675.000
jadi jawabannya B
Semoga membantu ^^
