Question

a) calculer la surface dun garage qui fait 10m de long par 9 m de larg et réponse en pi² !

Explanation:

Step1: Calculate area in m²

Area = length × width = $10 \times 9 = 90$ m²

Step2: Convert m² to ft² (pi² is likely typo for pieds carrés/ft², conversion factor: $1\ \text{m}^2 = 10.7639\ \text{ft}^2$)

$\text{Area (ft}^2\text{)} = 90 \times 10.7639$

Answer:

$968.751$ ft² (or approximately 969 ft²)

Note: "pi²" is assumed to be a typo for French "pieds carrés" (square feet), as pi squared ($\pi^2$) is a mathematical constant unrelated to area conversion here. If the question intended $\pi^2$ as a unit, the result would be $\frac{90}{\pi^2} \approx 9.14$ $\pi^2$ (m² per $\pi^2$ unit), but square feet is the logical intended unit for this context.
