Diketahui perbandingan jajar genjang=4:2 dan luas jajar genjang=160cm²

Tentukan panjang siai masing masing

Answer 1

• alas = 4x
• tinggi = 2x

Cari nilai x!

L = a × t

160 = 4x × 2x

160 = 8x²

x² = 160/8

x² = 20

x = √20

x = 2√5 cm

• alas = 4x = 4(2√5 cm) = 8√5 cm
• tinggi = 2x = 2(2√5 cm) = 4√5 cm
