Step-by-step Solution
Para resolver esta expresión, primero necesitamos convertir todas las medidas a la misma unidad. Vamos a convertir los decímetros (dm) a centímetros (cm) ya que 1 dm es igual a 10 cm.
Entonces, la expresión se convierte en:
\( \left. \begin{array} { l } { 34 \times 10 \, cm + 20 \times 10 \, cm } \\ { 124 \, cm + 12 \times 10 \, cm } \end{array} \right. \)
Ahora podemos simplificar la expresión:
\( \left. \begin{array} { l } { 340 \, cm + 200 \, cm } \\ { 124 \, cm + 120 \, cm } \end{array} \right. \)
Finalmente, sumamos los valores:
\( \left. \begin{array} { l } { 540 \, cm } \\ { 244 \, cm } \end{array} \right. \)
Por lo tanto, la expresión simplificada es \( 540 \, cm + 244 \, cm \).
Quick Answer
La expresión simplificada es \( 540 \, cm + 244 \, cm \).
