L layang-layang = di x d2 x 1/2 252 = BD x AC x 1/2 252 = 24 x AC x 1/2 252 = 12 x AC 21 cm= AC L ATD = 1/2 x A x t = 1/2 x 12 x 16 = 12 x 8 = 96 cm² L BCD = 1/2 x A x t = 1/2 x 24 x 5 = 12 x 5 = 60 cm²
252 = BD x AC x 1/2
252 = 24 x AC x 1/2
252 = 12 x AC
21 cm= AC
L ATD = 1/2 x A x t
= 1/2 x 12 x 16
= 12 x 8
= 96 cm²
L BCD = 1/2 x A x t
= 1/2 x 24 x 5
= 12 x 5
= 60 cm²
