2. 7/18 x 180 = 70°

3. K= s + s + s

18 = s + s + 1 + s + 2

18 = 3s + 3

18 – 3 = 3s

15 = 3s

15 : 3 = s

5 = s

a. 5

b. 5+1 = 6

c. 5+2 = 7

4.L = 1/2 x a x t

238 = 1/2 x 28 x t

238 = 14 x t

238 : 14 = t

17 cm = t

5. L = 1/2 x a x t

432 = 1/2 x 8p x 3p

432 x 2 = 24p²

864 = 24p²

p² = 864 : 24

p² = 36

p = √36

p = 6

alas = 8 x p

= 8 x 6 = 48 cm
