Jawaban:

1. L = ½ × a × t

= ½ × 8 × 5

= 40/2

= 20 cm²

2. L = ½ × a × t

30 = ½ × a × 10

a = 30 / ½ × 10

a = 30 / 5

a = 6 cm

3. L = ½ × a × t

= ½ × 6 × 15

= 90/2

= 45 cm²

4. L = ½ × a × t

= ½ × 5 × 12

= 60/2

= 30 cm²

5. L = ½ × a × t

54 = ½ × 9 × t

t = 54 / ½ × 9

t = 54 / 4,5

t = 12 cm

Semoga Membantu
