Responder:
Altura = 26
Base = 20
Explicación paso a paso:
Dado que :
Dejar :
Base = b
Altura = 6 + b
Área del rectángulo = base * altura
520 = b * (6 + b)
520 = 6b * b²
b² + 6b - 520 = 0
b² + 26b - 20b - 520 = 0
segundo (segundo + 26) - 20 (segundo + 26) = 0
b + 26 = 0
b = - 26
b - 20 = 0
b = 20
Ignorar negativo
b = 20
Altura = 20 + 6 = 26
