luas gabungan datar layang layang pake caranya

luas layang layang
= 1/2 x d1 × d2
1/2 x (3+3) x(7+4 )
1/2 x 6 x 11
1/2 x 66
33 cm

luas segi tiga
1/2 x a x t

1/2 x a x t
1/2 x 6 x 7
1/2 x42
21 cm

luas bangun gabungan
33 cm + 21 cm = 54 cm

== Jawaban ==
LL = ½ × d1 × d2
LL = ½ × ( 3 + 3 ) × ( 7 + 4 )
LL = ½ × 6 × 11
LL = 3 × 11
LL = 33 cm²

LS = ½ × a × t
LS = ½ × 6 × 7
LS = 3 × 7
LS = 21 cm²

LL + LS = 33 cm² + 21 cm²
= 54 cm²
