Bro. Kalo lebih, disoalnya pasti ada penjelasan lain.

Bisa aja itu cuma kesalahan gambar. Sekarang kalo emang d nya 14. Itu lingkaran nonjol dikit.

L Persegi Panjang = p * l =21 cm * 14 cm =294 cm² L Lingkaran =Diket = r =d : 2=14 cm : 2 =7 cm L=π * r * r =22/7 * 7 cm * 7 cm L=154 cm² L arsir =294 - 154 =140 cm² Jadi, L arsir =140 cm²

Please, let me answer your question :)___________________________
Lingkaran :
- d= 14 cm > r= 7 cm
Persegi Panjang :
- p= 21 cm
- l= 14 cm
Ditanya= L arsir?
LP= p x l
LP= 21 x 14
LP= 294 cm²
LL= πr²
LL= 22/7 x 7 x 7
LL= 22 x 7
LL= 154 cm²
L arsir = 294-154 = 140 cm²

Hopefully this is the best for you :)

=21 cm * 14 cm =294 cm²
L Lingkaran =Diket = r =d : 2=14 cm : 2 =7 cm
L=π * r * r =22/7 * 7 cm * 7 cm
L=154 cm²
L arsir =294 - 154 =140 cm²
Jadi, L arsir =140 cm²
