buat siqng ini nihh

Answer 1

Luas BAC = 1/2 . a . t
= 1/2 . (11 + 5) . (7 + 5)
= 1/2 . 16 . 12
= 8 . 12
= 96 cm²

Luas AED = 1/2 . a . t
= 1/2 . 5 . 5
= 1/2 . 25
= 12, 5 cm²

Luas BCDE = 96 - 12,5
= 83,5 cm²

Answer 2

Luas segitiga kecil
= 1/2 x 5 x 5 = 12,5kuadrat
luas segitiga yg besar
= 1/2 x 16 x 12 = 96cmkuadrat

luas yg diarsir
= 96 - 12,5 = 83,5cmkuadarat
