Question

the dimensions of a room are given as 9.6 meters by 7.7 meters, to the nearest 10 cm. what area of carpet should be purchased to make sure it covers all the room?

Explanation:

Step1: Identificar la fórmula del área

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

Step2: Sustituir valores

Dado que $l = 9.6$ m y $w=7.7$ m, entonces $A=9.6\times7.7$.

Step3: Realizar el cálculo

$A = 9.6\times7.7=73.92$ m².

Answer:

$73.92$ m²
