The area of the base of a rectangular prisim four and three fourths and the height of two and one third what is the volume
VikaD [51]
Data:
A_{base} = 4 \frac{3}{4} = \frac{4*4+3}{4} = \frac{16+3}{4} \to A_{base} = \frac{19}{4}

h (height) = 2 \frac{1}{3} =  \frac{3*2+1}{3} = \frac{6+1}{3} \to h (height) = \frac{7}{3}
v (volume) = ?

Formula: V =  A_{b}*h

Solving:
V = A_{b}*h
V =  \frac{19}{4} * \frac{7}{3}
V =  \frac{133}{12}
V = 11.08333....
\boxed{\boxed{V \approx 11.08}}\end{array}}\qquad\quad\checkmark

¿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
