Jawab:b. 1 : 4
Penjelasan:a = alas segitigab = sisi atas trapesiumt = tinggi segitiga dan trapesium
Luas dariSegitiga. at/2Trapesium. (ᵃ/₂ + 2b)(t/2)
Jika luasnya samaat/2 = (ᵃ/₂ + 2b)(t/2)a = (ᵃ/₂ + 2b)a = ½ (a + 4b)2a = a + 4b2a - a = 4ba = 4bb = ᵃ/₄
Ditanya b : a= ᵃ/₄ : a= a : 4a= 1 : 4 (opsi b)

Jawab:
b. 1 : 4
Penjelasan:
a = alas segitiga
b = sisi atas trapesium
t = tinggi segitiga dan trapesium
Luas dari
Segitiga. at/2
Trapesium. (ᵃ/₂ + 2b)(t/2)
Jika luasnya sama
at/2 = (ᵃ/₂ + 2b)(t/2)
a = (ᵃ/₂ + 2b)
a = ½ (a + 4b)
2a = a + 4b
2a - a = 4b
a = 4b
b = ᵃ/₄
Ditanya b : a
= ᵃ/₄ : a
= a : 4a
= 1 : 4 (opsi b)
