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
