288 inches
68 inches
18 inches
\frac{1}{18} inch

Explanation:

Step1: Reescribir la fórmula para b

Dado $A = bh$, despejamos $b$: $b=\frac{A}{h}$.

Step2: Sustituir valores de A y h

Tenemos $A = 72$ pulgadas al cuadrado y $h = 4$ pulgadas. Entonces $b=\frac{72}{4}$.

Step3: Calcular el valor de b

$\frac{72}{4}=18$ pulgadas.
