Luas Jajargenjang = alas x tinggi

alas = 25 cm - 9 cm = 16 cm
tinggi = 12 cm

L = a x t
L = 16 cm x 12 cm
L = 192 cm²

Jawaban D

10)
Luas dua buah 1/4 Lingkaran
r = 10 dm

L = 2 x 1/4 x π x r²
L = 1/2 x 3,14 x 10²
L = 1/2 x 3,14 x 100
L = 1/2 x 314
L = 157 dm²

Luas belah ketupat
D1 = 8 dm + 8 dm = 16 dm
D2 = 6 dm + 6 dm = 12 dm

Luas = 1/2 x D1 x D2
L = 1/2 x 16 dm x 12 dm
L = 8 dm x 12 dm
L = 96 dm²

Luas keseluruhan
L = 157 dm² + 96 dm²
L = 253 dm²
