Multiple the known quantity for one apartment, by the number of apartments:

[tex]Carpet_{total} = \frac{carpet}{apartment} \times n_{apartments}[/tex]
[tex]Carpet_{total} = 36\frac{yd^{2}}{apartment} \times 25apartments[/tex]
[tex]Carpet_{total} = 900yd^{2}[/tex]

Hello!

You can make a proportion

[tex] \frac{1}{36} = \frac{25}{x} [/tex]

Cross multiply

36 × 25 = 900

900 ÷ 1 = 900

Answer ⇒ D. 900 square yards
