3. diket : alas = 4y , tinggi = 3y , dan L = 192 cm² ditany: alas ? tinggi ? jawab : L = a × t 192 cm ² = 4y × 3y 192 cm ² = 12y² 192cm² : 12 = 12y² : 12 16 = y² √16 = y 4 = y alas = 4.y = 4×4 = 16 ting = 3.y = 3×4 = 12 5.diket : tinggi = 2x , alas = x , L = 162 cm² ditany : alas ? ting ? jawab : L = a × t 162 cm² = x × 2x 162 cm² = 2x² 162 cm² : 2 = 2x² : 2 81 = x² √81 = x 9 = x alas = x = 9 cm ting = 2x = 2.9cm = 18 cm
alas = 4y , tinggi = 3y , dan L = 192 cm²
ditany:
alas ? tinggi ?
jawab :
L = a × t
192 cm ² = 4y × 3y
192 cm ² = 12y²
192cm² : 12 = 12y² : 12
16 = y²
√16 = y
4 = y
alas = 4.y = 4×4 = 16
ting = 3.y = 3×4 = 12
5.diket :
tinggi = 2x , alas = x , L = 162 cm²
ditany :
alas ? ting ?
jawab :
L = a × t
162 cm² = x × 2x
162 cm² = 2x²
162 cm² : 2 = 2x² : 2
81 = x²
√81 = x
9 = x
alas = x = 9 cm
ting = 2x = 2.9cm = 18 cm
