B. Persegi - L = sxs = 5 cm x 5 cm = 25 cm kuadrat - K = 4xsisi = 4x(5 cm) =20 cm C. Persegi panjang - L = pxl = 18 cm x 16 cm = 288 cm kuadrat - K = 2 (p+l) = 2 (18+16) = 2 (34) = 68 cm D. Persegi panjang - L = pxl = 25 cm x 9 cm = 225 cm kuadrat - K = 2 (p+l) = 2 (25+9) = 2 (34) = 68 cm

B. Luas = Sisi × Sisi = 5 × 5 = 25 cm Keliling = 4 × Sisi = 4×5 = 20 cm C. Luas = P × L = 18×16 = 288 cm keliling = 2 × (P+L) = 2 × (18 + 16) = 2 × 34 = 68 cm D. Luas = P×L = 25×9 = 225 cm keliling = 2×(25+9) = 2 × 34 = 68 cm
- L = sxs
= 5 cm x 5 cm
= 25 cm kuadrat
- K = 4xsisi
= 4x(5 cm)
=20 cm
C. Persegi panjang
- L = pxl
= 18 cm x 16 cm
= 288 cm kuadrat
- K = 2 (p+l)
= 2 (18+16)
= 2 (34)
= 68 cm
D. Persegi panjang
- L = pxl
= 25 cm x 9 cm
= 225 cm kuadrat
- K = 2 (p+l)
= 2 (25+9)
= 2 (34)
= 68 cm
Keliling = 4 × Sisi = 4×5 = 20 cm
C. Luas = P × L = 18×16 = 288 cm
keliling = 2 × (P+L) = 2 × (18 + 16) = 2 × 34 = 68 cm
D. Luas = P×L = 25×9 = 225 cm
keliling = 2×(25+9) = 2 × 34 = 68 cm
Maaf klo salah :D
