Answer 1

27cm + 19cm x 18 cm =46 x 18 = 828cm :2 = 414cm

3,5m +1,7m x 2,2 =5,2 x 2,2=11,44m :2=5,72m

38cm + 25cm x 17cm =63 x 17=1071cm :2=535,5m

34dm + 9m x 46dm =3,4m+9m x 4,6m=12,4 x 4,6=57,04m:2= 28,52m

4dm + 45cm x 1dm x 3,4dm =4dm+4,5dm x 1dm x 3,4dm=8,5dm x 1dm x 3,4dm=28,9dm : 2=14,45dm

1,7dm + 2,6dm x 1,9dm =4,3 x 1,9=8,17dm :2=4,085dm

Answer 2

27cm + 19cm x 18 cm =46cm×18cm=828cm²÷2=414cm²
3,5m +1,7m x 2,2 =5,2m×2,2m=11,44m²÷2=5,72m²
38cm + 25cm x 17cm =63cm×17cm=1071cm²÷2=535,5cm²
34dm + 9m x 46dm =3,4m+9m×4,6m=12,4m×4,6m=57,04m²÷2=28,52m²
4dm + 45cm x 1dm x 3,4dm =?
1,7dm + 2,6dm x 1,9dm =4,3dm×1,9dm=8,17dm²÷2=4.085dm²
