Luas trapesium = (a+b : 2) x t = ( 9+16 :2) x 14 = 12,5 x 14 = 175,0 Luas 1/2 lingkaran = 1/2 x phi x jari" x jari" jari-jari lingkaran = diameter : 2 = 14:2 = 7 L. 1/2 lingkaran = 1/2 x 22/7 x 7 x 7 = 1/2 x 154 = 77 Luas gabungan = 175 + 77 = a. 252
= ( 9+16 :2) x 14
= 12,5 x 14
= 175,0
Luas 1/2 lingkaran = 1/2 x phi x jari" x jari"
jari-jari lingkaran = diameter : 2
= 14:2
= 7
L. 1/2 lingkaran = 1/2 x 22/7 x 7 x 7
= 1/2 x 154
= 77
Luas gabungan = 175 + 77
= a. 252
