Jawaban:

c. s = 14m dan K = 56m

Penjelasan dengan langkah-langkah:

3x-4 = 2x+2

3x-2x = 2+4

x=6

sisi belah ketupat = 3x-4

= 3(6)-4

= 14m

keliling = 14 x 4

= 56m

Belah ketupat memiliki sisi sama panjang

  • Nilai x

3x - 4 = 2x + 2 cm

3x - 2x = 2 + 4 cm

x = 6 cm

  • Panjang sisi

s = 3x - 4 cm

s = 3(6) - 4 cm

s = 18 - 4 cm

s = 14 cm

  • Keliling

= 4 × s

= 4 × 14 cm

= 56 cm
