Penjelasan dengan langkah-langkah:
panjang sisi miring
= √12² + 16²
= √144 + 256
= √400
= 20 cm
panjang sisi miring satu lagi
= √12² + 5²
= √144 + 25
= √169
= 13 cm
__
K = s1 + s2 + s3 + s4
k = 20 + 20 + 13 + 13
k = 40 + 26
k = 66 cm
__
L = 1/2 × d2 × d2
L = 1/2 × (12.2) × (16+5)
L = 1/2 × 24 × 21
L = 12 × 21
L = 252 cm²
Penjelasan dengan langkah-langkah:
[tex]k = s1 + s2 + s3 + s4[/tex]
[tex]k = \sqrt{12 {}^{2} + 5 {}^{2} } + \sqrt{16 {}^{2} + 12 {}^{2} } \times 2 \: (kaena \: ada \: sisi \: sejajar)[/tex]
[tex]k = \sqrt{169} + \sqrt{400} \times 2[/tex]
[tex]k = 13 + 20 \times 2[/tex]
[tex]k = 33 \times 2[/tex]
[tex]k = 66[/tex]
[tex]l = \frac{1}{2} \times d1 + d2[/tex]
[tex]l = \frac{1}{2} \times 12 \times 5[/tex]
[tex]l = \frac{1}{2} \times 60[/tex]
[tex]l = 30[/tex]
