Ответ:
El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.
Step-by-step explanation:
Para empezar debes tener en cuenta que las medidas tienen que estar en la misma magnitud; por lo tanto en este caso la unidad de medida elegida a utilizar es centímetros. Por lo que el lado que mide 6,3 dm será expresado en cm. Entonces se puede aplicar la siguiente regla de tres simple: si 1 dm equivale a 10 cm, entonces 6,3 dm a cuántos cm equivale?
cm=63
Entonces 6,3 dm= 63 cm
El perímetro es la distancia alrededor de una figura, mientras que el área es las unidades cuadradas dentro de una figura.
El Perímetro de un rectángulo es igual a la suma de todos sus cuatro lados. Un rectángulo siempre tiene dos pares de longitudes iguales. Entonces en este caso se obtiene:
63 cm + 63 cm + 48 cm + 48 cm= 222 cm
El área de un rectángulo es el producto de la longitud de los lados. Entonces en este caso se obtiene:
63 cm* 48 cm= 3024 cm²
El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.
