‼️ POIN BESAR ‼️

Penjelasan dengan langkah-langkah:

1) sisa kawat = 1,5 x 100 – 4 x (15+10+8)

= 150 – 4 x 33

= 150 – 132

= 18 cm

2) Lp = 2x8x15 + (8+15+17)x20

Lp = 240 + 800

Lp = 1.080 cm²

3) Lp = 10² + 2x10x13

= 100 + 260

= 360 cm²

4) Jangkauan = 90 – 40 = 50

5) n(s) = 6

n(prima) = 3

P(prima) = 3/6 = ½
