Remember you can do anything to an equation as long as you do it to both sides

5c+16.5=13.5+10c
minus 5c both sides
16.5=13.5+5c
minus 13.5 from both sides
3=5c
divide both sides by 5
3/5=c

<span> 5c + 16.5 = 13.5 + 10c
 
16.5 + 5c = 13.5 + 10c

 16.5 + 5c = 13.5 + 10c
 
16.5 + 5c + -10c = 13.5 + 10c + -10c
 
 5c + -10c = -5c 16.5 + -5c = 13.5 + 10c + -10c

10c + -10c = 0 16.5 + -5c = 13.5 + 0 16.5 + -5c = 13.5
 
 16.5 + -16.5 + -5c = 13.5 + -16.5

:16.5 + -16.5 = 0.0 0.0 + -5c = 13.5 + -16.5 -5c = 13.5 + -16.5
 
13.5 + -16.5 = -3 -5c = -3
 
Divide each side by '-5'.
 
c = 0.6 or 3/5</span>

¿Cuál es el área de un rectángulo, sabiendo que su perímetro mide 24 cm y que su base es el triple de su altura?
Brrunno [24]

Answer:

El área del rectángulo es:

27 cm²

Step-by-step explanation:

Consideración:

La formula del perímetro de un rectángulo es:

p = 2(altura + base)

Planteamiento:

24 = 2(a+b)

b = 3a

a = longitud de la altura del rectángulo

b = longitud de la base del rectángulo

Desarrollo:

sustituyendo el valor de la segunda ecuación del planteamiento en la primer ecuación del planteamiento:

24 = 2(a + 3a)

24/2 = 4a

12 = 4a

a = 12/4

a = 3 cm

de la segunda ecuación del planteamiento:

b = 3a

b = 3*3

b = 9 cm

Comprobación:

de la primer ecuación del planteamiento:

24 = 2(3+9)

24 = 2*12

Respuesta:

la formula del área de un rectángulo es:

A = base * altura

A = 9cn * 3cm

A = 27cm²
