Lady bird [3.3K]

Answer:

$A = 128\,cm^{2}$

Step-by-step explanation:

El área del rectángulo se halla a través de la siguiente fórmula: (The area of the rectangle is obtained by the following formula:)

$A = (40\,cm - 2\cdot x)\cdot x$

Donde el área y $x$ se miden en centímetros cuadrados y centímetros, respectivamente. (Where area and $x$ are measured in square centimeters and centimeters, respectively)

Ahora, $x$ se reemplaza y se encuentra el valor numérico del área: (Now, $x$ is substituted and numerical value of area is finally determined:)
