Pembahasan :
Luas persegi panjang
= p × l
= 25 cm × 18 cm
= 450 cm^2
Luas lingkaran
= 2 × 1/4 × phi × r^2
= 2 × 1/4 × 22/7 × 7 × 7
= 77 cm^2
Luas daerah yang diarsir
= Luas persegi panjang - Luas lingkaran
= 450 cm^2 - 77 cm^2
= 373 cm^2
Good Luck ^_^

Jawab :L. ¼ lingkaran = 1/4 × × π × r²
= 1/4 × 22/7 × 7²
= 5,5 × 7
= 38,5 cm² × 2
= 77 cm²
L persegi panjang = p × l
= 25 × 18
= 450 cm²
jadi,,,
L daerah yang diarsir =
= L. persegi panjang - L. lingkaran
= 450 - 77
= 373 cm²
semoga membantu ya gan......
