perhatikan jajar genjang ABCD!
Penjelasan dengan langkah-langkah:
a) Keliling = 2 x ( AD + DC )
= 2 x (16 + 28)
= 2 x 44
= 88 cm
b) Luas = AD x DF
= 16 x 21
= 336 cm²
c) DE = 16 x 21/28
= 16 x ¾
= 3 x 16/4
= 3 x 4
= 12 cm
a
2( 16 + 28)
2( 44)
88 cm
b.
AD X DF
16 x 21
336 cm²
c
panjang DE
21/28 x 16
3/4 x 16
48/4
12 cm
