El perímetro es 28cm y el ancho es de 6 cm cuál es al alto
Snowcat [4.5K]

Answer:

El mayor lado del rectángulo es de 10 cm

Explicación paso a paso:

Perímetro de un rectángulo: es el doble de la suma de sus lados

P = 2 (a+b)

a: es el ancho del rectángulo

b: es el largo del rectángulo

Uno de los lados es 6cm mas que el otro lado

b= a + 6 cm

Sustituimos en la ecuación de perímetro:

28cm /2 = a+a+6cm

14cm = 2a +6 cm

14cm-6cm = 2a

a = 4 cm

b = 10cm

El mayor lado del rectángulo es de 10 cm
