Tolong jawab ya dgn cara karna bsk dikumpulin

no.2.luas 1(trapesium)
= (a+b)×t/2
=(18+(14+4+4))×14/2
=(18+22)×14/2
=40×14/2
=40×7
=280
luas 2 :(1/2 lingkaran)
=1/2×(22/7)×7×7
=1/2×154
=77

=280-77=203

no.5.luas 1(trapesium)
=(a+b)×t/2
=(12+(12+5+5))×16/2
=(12+22)×8
=34×8
=272
luas 2 (1/2 lingkaran ×2=satu lingkaran)
=3.14×6×6
=113

=272-113=159

semoga membantu :D
