hii, bisa tolong bantu soal ini? thankyouu
Jawaban:
232 cm²
Penjelasan dengan langkah-langkah:
AB = ED
Luas ABDE = a x t
= AB x EF
= 14 x 8
= 112 cm²
AF = ED - FB
= 14 - 8
= 6 cm
AE = √AF²+EF²
= √6²+8²
= √36+ 64
= √100
= 10 cm
AE = BD
BC = √DC²-BD²
= √26²-10²
= √676-100
= √576
= 24 cm
Luas BCD = ½ x a x t
= ½ x BD x BC
= ½ x 10 x 24
= 120 cm²
Luas ABCDE = L.ABDE + L.BCD
= 112 + 120
= 232 cm²
Semoga membantu
