Penjelasan dengan langkah-langkah:
L trapesium = (a+b)/2 × t = (16+22) /2 × 7
= 38/2 x 7
= 19 x 7
=133 cm²
L 1/2 lingkaran = 1/2 × π r²
= 1/2 x 22/7 × 35/10 × 35/10
=26950/1400
=19, 25 cm²
L diarsir = L trap - L 1/2 lingkaran
= 133 - 19,25
= 113,75 cm²
mangkanya belajar biar bisa menghitung
kalau hanya mengandalkan brainly ga pinter
