AVprozaik [17]

Answer:

Total = 300

Number of teachers = 300 - (137+145) = 18

Percentage of teachers = (number of teachers÷total)× 100%

Si el largo de un rectángulo mide el doble del ancho que es "a", ¿cuál es su área?

rosijanka [135]

Answer:

El área es 2 veces el cuadrado del ancho del rectángulo.

Step-by-step explanation:

El área de un rectángulo viene dado por:

$A = a*l$

En donde:

a: es el ancho

l: es el largo

Si el largo es el doble del ancho:

$l = 2a$

Entonces el área es:

$A = a*l = a*(2a) = 2a^{2}$

Por lo tanto, el área es 2 veces el cuadrado del ancho del rectángulo.
