luas daerah gambar diatas..... cm² (π = 3,14)

[tex]3.14 \times12 \times 12 \times \frac{1}{2} = 13.48 \times 6 = 80.88 + 33 \times 24 = 872.88[/tex]

L. Persegi panjang = p × l

[tex] = 33 \: cm \: \times \: 24 \: cm \: [/tex]
[tex] = 792 \: cm ^{2} [/tex]
L. 1/2 Lingkaran =
[tex]\pi \times r \times r \times \frac{1}{2} [/tex]
[tex] = 3.14 \times 12 \times 12 \times \frac{1}{2} [/tex]
[tex] = 452.16 \div \frac{1}{2} [/tex]
[tex] = 226.08 \: cm ^{2} [/tex]
L. Total = L I + L II
[tex] = 792 \: cm ^{2} + 226.08 \: cm ^{2} [/tex]
[tex] = 1018.08 \: cm ^{2} [/tex]
