Luas persegi = 14 x 14 = 196cm^2 luas lingkaran = phi x r^2 = 22/7 x 7 x 7 = 154cm^2 luas daerah diarsir = 196 - 154 = 42 cm^2
semoga membantu

Luas persegi = r × r = 14 × 14 = 196 cm (bangun I) luas lingkaran = phi × r × r = 22/7 × 7 × 7 = 154 cm (bangun II) daerah di arsir = bangun I - bangun II = 196 - 154 = 42 cm (A)
luas lingkaran = phi x r^2 = 22/7 x 7 x 7 = 154cm^2
luas daerah diarsir = 196 - 154 = 42 cm^2
semoga membantu
= 14 × 14
= 196 cm (bangun I)
luas lingkaran = phi × r × r
= 22/7 × 7 × 7
= 154 cm (bangun II)
daerah di arsir = bangun I - bangun II
= 196 - 154
= 42 cm (A)
