Jawaban:

a.Luas ABCD=AB XBC

=12cm x 5 cm

=60 cm2

KL kuadrat= KMkuadrat – LM kuadrat

KLkuadrat= 169-25

= 144

KL= 12

Luas KLMN= KL X LM

= 12 cm x 5 cm

= 60 cm2

jadi luas ABCD = luas KLMN

b.keliling ABCD = keliling KLMN

2x(p+l). =. 2 x(p+l)

2x(12+5). = 2 x (12+5)

2×17. = 2x 17

34. =. 34

c. ABCD =~ KLM

karena panjang AB=CD=KL=MN

BC=DA=LM=NKmaks ABCD=KLMN
