1.

  • L persegi panjang (kanan kiri)

p = 1 cm

l = 7 cm

= 2 × (p × l)

= 2 × (1 × 7)

= 2 × 7

= 14 cm²

  • L persegi panjang (tengah)

p = 2 cm

/ = 7 3 3 = 1 cm

= p × l

= 2 × 1

= 2 cm²

  • L kertas (huruf H)

14 cm² + 2 cm²

= 16 cm²

4.

  • L segitiga (kiri)

= ½ × a × t

= ½ × 6 × 10

= ½ × 60

= 30 m²

  • L segitiga (kanan)

= ½ × a × t

= ½ × 12 × 20

= ½ × 240

= 120 m²

  • L kebun

30 m² + 120 m²

= 150 m²

  • Harga jual

Rp 3.000.000 × 150

= Rp 450.000.000
