Tolong do kerjain semuanya

3. Luas kebun = 2 hektare
Lebar = 125m
Panjang = ?
Luas persegi panjang = p × l
2 hektare = 20.000m² : 125m
panjang = 160m

4. Panjang = 3/2 × 54cm²= 81cm
Lebar = 2/3 × 54cm²= 36cm

5. L1 = p × l
= 8cm × 16cm
= 128cm²
L2 = S × S
= 8cm × 8cm
= 64cm²
Luas seluruhnya = 128cm² + 64cm²
= 192cm²
K = S1 + S2 + S3 + S4 + S5 + S6
= 8cm + 8cm + 8cm + 8cm + 16cm + 16cm
= 64cm

Semoga membantu dan bermanfaat ya…
