Tolong di bantu kak besok dikumpul remedial soalnya hehehe

Luas trapesium = 1/2 ( a+b) x t = 1/2 ( 14+26 ) x 16 = 1/2 ( 40 ) x 16 = 20x 16 = 320 cm² sisi miring = d d² =a²+b² =16² +12² ( 12 dari 26 - 14 ) =256 +144 = 400 d =√400 = 20 cm Luas 1/2 lingkaran = 1/2 xπr² = 1/2 x 3,14 x 10² = 1/2 x 3,14 x 100 = 1/2 x 314 = 157 cm² luas seluruhnya = 320+157 =477 cm²
= 1/2 ( 14+26 ) x 16
= 1/2 ( 40 ) x 16
= 20x 16
= 320 cm²
sisi miring = d
d² =a²+b²
=16² +12² ( 12 dari 26 - 14 )
=256 +144
= 400
d =√400
= 20 cm
Luas 1/2 lingkaran = 1/2 xπr²
= 1/2 x 3,14 x 10²
= 1/2 x 3,14 x 100
= 1/2 x 314
= 157 cm²
luas seluruhnya = 320+157
=477 cm²
semoga bantuu yaa
