Question

the dimensions of a room are given as 9.2 meters by 10.9 meters, to the nearest 10 cm. what area of carpet should be purchased to make sure it covers all the room? area = 101.4 m² area = 101 m² area = enter your next step here m² so close! can you try again checking for rounding errors? you can redo the calculations and only round at the last step.

Explanation:

Step1: Identificar la fórmula de área

El área de un rectángulo se calcula como $A = l\times w$, donde $l$ es la longitud y $w$ es el ancho.

Step2: Sustituir valores

Dado que $l = 10.9$ m y $w = 9.2$ m, entonces $A=10.9\times9.2$.

Step3: Realizar la multiplicación

$10.9\times9.2 = 100.28$ m².

Step4: Redondear

Redondeando a la unidad más cercana, $A\approx100$ m².

Answer:

$100$ m²
