tolong mas matematikadan ya makasih
Soal 1
²²/7 × j² = 616 cm²
j² = 616 cm² ÷ ²²/7
j² = 616 cm² × ⁷/22
j² = 196 cm
j = 14 cm
--
Soal 2
²²/7 × j² = 38,5 cm²
j² = 38,5 cm² ÷ ²²/7
j² = 38,5 cm² × ⁷/22
j² = 12,25 cm
j = 3,5 cm
--
Soal 3
3,142 × j² = 706,95 cm²
j² = 706,95 cm² ÷ 3,142
j² = 225 cm
j = 15 cm

Penjelasan dengan langkah-langkah:
1.
22/7 × j² = 616
j² = 616 × 7/22
j² = 4312/12
j = √196
j = 14 cm
2.
22/7 × j² = 38,5
j² = 38,5 × 7/22
j² = 269,5/22
j² = 12,25
j = √12,25
j = 3,5 cm
3.
3,142 × j² = 706,95
j² = 706,95/3,142
j = √225
j = 15 cm
