Question

The ratio of the length to the width of a rectangular advertising display is approximately $3.3$ to $2.$ If the width of the display is $8$ meters, what is the approximate length of the display, in meters?

• A. $7$
• B. $11$
• C. $13$
• D. $16$
• E. $26$

Answer 1

The correct option is C $13$

For rectngular advertising display

Length : Width $=3.3:2$

Width of display $=8m$

$\Rightarrow \frac{Length}{Width}=\frac{3.3}{2}\Rightarrow \frac{Length}{8m}=\frac{33}{20}\Rightarrow Length=\frac{33\times 8m}{20}=\frac{66}{5}m=13.2m\simeq 13m$
