tolong jawab ya ka ??

Luas persegi = S²

L = 144 cm²
S² = √144
S = 12 cm

Keliling persegi = 4S
= 4 × 12
= 48 cm

1. p = 24 cm
l= 15 cm
keliling = 2(p+l) = 2(24cm+15cm)
= 2 × 39 cm= 78 cm (jawaban A)

2. luas = 144 cm2
sisi = akar dari 144 cm2 = 12 cm
keliling = 4 × sisi = 4 × 12 cm = 48 cm
(jawaban A)

3. keliling = 96 cm
sisi = 96 cm ÷ 4 = 24 cm
luas=sisi×sisi = 24 cm × 24 cm = 576 cm2
(jawaban C)
