Question

Dicari luas dan keliling

Answer 1

3) Ls = 42 × 42
= 1.764 cm²
L½ lngkran = ½ × 22/7 × 21 × 21
= 693 cm²
jadi L bngun = 1.764 - 693
= 1.071 cm²
kel bngun = kel ½ lngkran + (42 × 3)
= (½ . 22/7 . 42) + 126
= 66 + 126 = 192 cm

4) L1 = a . t
= 8 . 10 = 80cm²
L2 = ½ . 8 . 6
= 24 cm²
L ttl = 80 + 24 = 104 cm²
kel = 8 + 12 +6 + 10 + 12
= 48 cm
