10.Rumus Luas Segitiga = Alas x Tinggi x 1/2
=Alas = 10 Cm
=Tinggi = 14 Cm
=14 Cm x 10 Cm x 1/2
=14 ÷ 1/2
=7 Cm
=7 Cm x 10 Cm
=70 Cm²
Rumus Luas Lingkaran = phi x r x r
=R=Jari-Jari
Jari-Jari = 1/2 x Diameter
=r = 1/2 x 14
= 7 Cm
=1/2 x 22/7 x 7 x 7
=11 x 7
=77 Cm²
Luas Total Bangun Daerah Tersebut = 70 Cm² + 77 Cm²
=147 Cm²
