Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

1.)

A. 10 - 5 = 5 cm

t² = 13² - 5²

t² = 169 - 25

t² = 144

t = 12 cm

L = a + b × t

2

= 5 + 10 × 12

2

= 90 cm

K = 5 + 13 + 10 + 12 = 40 cm

B. L = a + b × t

2

= 10 + 20 × 12

2

= 180 cm

20 - 10 = 10

= 10 ÷ 2 = 5 cm

X² = 12² + 5²

X² = 144 + 25

X² = 169

X = 13 cm

K = 10 + 20 + 13 + 13 = 56 cm

C. 20 - 12 = 8

t² = 10² - 8²

t² = 100 - 64

t² = 36

t = 6 cm

L = a + b × t

2

= 12 + 20 × 6

2

= 96 cm

K = 12 + 10 + 20 + 6 = 48 cm

D. 26 - 10 = 16

= 16 ÷ 2 = 8 cm

t² = 17² - 8²

t² = 289 - 64

t² = 225

t² = 15

L = a + b × t

2

= 10 + 26 × 15

2

= 270 cm

K = 10 + 26 + 17 + 17 = 70 cm

2.) 30 = a + b × t

2

30 = 4 + 8 × t

2

60 = 12 × t

5 = t

3.) 150 = a + b × t

2

150 = 10 + b × 20

2

300 = 10 + b × 20

15 = 10 + b

5 = b
