a. BD : c: a2 + b2 = c2
13 ^{2} [/tex] = [tex] 5^{2} [/tex] + [tex] b^{2} [/tex]
169 = 25 + [tex] b^{2} [/tex]
[tex] b^{2} [/tex] = 169 - 25 = 144
BD : [tex] \sqrt{144} [/tex] = 12
b. AD : [tex] c^{2} [/tex] = [tex] a^{2} [/tex] +[tex] b^{2} [/tex]
AD : [tex] 16^{2} [/tex] + [tex] 12^{2} [/tex]
: 400
: [tex] \sqrt{400} [/tex]
AD : 20
c. Kll = A+B+C+D = 54 cm
d. L Bangun 1 = [tex] \frac{1}{2} [/tex] x a x t = [tex] \frac{1}{2} [/tex] x16 x12 = 96
L Bangun 2 = [tex] \frac{1}{2} [/tex] x a x t = [tex] \frac{1}{2} [/tex] x 5 x12 = 30
L bangun ABCD = 96+30 = 126 cm
