1-10 tolong ya dikerjain

1 ) K = K.PP + K.ST
K = 25 cm + 32 cm + 26 cm + 26 cm + 32 cm
K = 141 cm (d)

2 ) K = K.ST - K.½L
K = (28 cm + 28cm + 7 cm + 7 cm ) - (3,14.½.14 cm)
K = 70 cm - 22 cm
K = 48 cm (a)

3 ) K = K.JG + K.LL
K = 35 cm + 40 cm + 35 cm + 20 cm + 20 cm + 35 cm
K = 185 cm (c)

4 ) K. PP = 2 (p+l)
K. PP = 2 (42 + 37) m
K. PP = 158 m (b)

5 ) K. PP = 2 (p+l)
K. PP = 2 (85 + 24) m
K. PP = 218 m (c)

6 ) K. PP = 2 (p+)
K. PP = 2 (20 + 15) m
K. PP = 70 m (b)

7 ) L = L.P + L.PP
L = (15 x 15) + (30 x 15)
L = 225 cm² + 450 cm²
L = 675 cm² (a)

8 ) L = L. ST + L. PP
L = (25 x 10 x ½) + (25 x 20)
L = 125 cm² + 500 cm²
L = 625 cm² (b)

9 ) L = L. PP + L. L
L = (8 x 20) + (3,14 x 20 x 20 x ¼)
L = 160 cm² + 314 cm²
L = 474 cm² (a)

10 ) L = L. PP + L. ST
L = (12 x 10) + (6 x 12 x ½)
L = 120 cm + 36 cm
L = 156 cm² (b)
