= 784 cm²
L lingkaran = 22/7 x 14 x 14 x 1/2
= 22 x 2 x 14 x 1/2
= 616 x 1/2
= 308 cm²
L arsir = 784 - 308
= 476 cm²
Luas persegi dikurangi luas setengah lingkaran
L. persegi = s x s
= 28 x 28
= 784 cm2
L. setengah lingkaran =
phi x r2 / 2
22/7 x 14 x 14 /2
11 x 14 = 154 cm2
784 cm - 154 cm = 630 cm2
