sama cara nya yah....

4.
●Luas {arsir} = 20 × 14 = 280 cm2
luas = 2 × 1/2 × 7 × 7 × 22/7 = 7 × 22 = 154 cm2
= 280 - 154 = 126 cm2
●keliling {arsir} = 2 × ( 20 + 14 ) = 2 × 34 = 68 cm
keliling = 2 × 1/2 × 14 × 22/7 = 2 × 22 = 44 cm
= 68 - 44 = 24 cm

5.
●Luas l = 1/2 × ( 17+10 ) × 6 = 27 × 3 = 81 cm2
luas ll = 1/2 × 6 × 7 = 3 × 7 = 21 cm2
= 81 + 21 = 102 cm2
