26. Luas 1/2 lingkaran
= 1/2 x phi x r²
= 1/2 x 3,14 x 10 x 10
= 1/2 x 314
= 157 cm²

Luas persegi panjang
= p x l
= 50 x 20
= 1000 cm²

Luas gabungan
= 157 cm² + 1000 cm²
= 1157 cm²
Opsi → B

27. Alas
= (14 - 8) : 2
= 6 : 2
= 3 cm

Panjang sisi miring
= √3² + 4²
= √9 + 16
= √25
= 5 cm

Keliling trapesium
= 8 + 14 + 5 + 5
= 22 + 10
= 32 cm
Opsi → C [tex] [/tex]
