jawabannya sama aja...
kalo g jelas,liat yg satunya lagi....
1/4×88cm×28cm
22cm×28cm
616cm²(B)
25)luas persegi = s²
L=21cm×21cm=441cm²
luas lingkaran=1/4×22/7×21cm×21cm
L=1/4×66cm×21cm
L=16,5cm×21cm
L=346,5cm²
jadi luas bangun gabungan = 441cm²+346,5cm²=787,5cm²(C)
26)Luas persegi panjang = 45m×32m=1.440m²
luas persegi =(32m×2)=64m
L=64cm×64cm
L=4.096m²
jadi selisihnya =4.096-1.440=2.656m²(D)
27)luas permukaan =2×(p×l)+(p×t)+(l×t)
=2×(162cm)+(216cm)+(108cm)
=2×(486cm)
=972cm³(D)
