El patio de butacas de una sala de cine tiene las mismas filas que columnas .Si el aforo es de 121 personas cuantas filas tiene la sala de cine ?
Respuestas
Aforo = 121 personas
Número de filas = Número de columnas
Representamos con "N" al número buscado.
N (Filas) × (N) Columnas = 120
N × N = 120
N² = 120
√N² = √120
N = √ 120
N = 11
Son 11 filas y 11 columnas.
11 × 11 = 121
R. La sala de cine tiene 11 filas de butacas.
