Chapter 1.3, Problem 18Q

To determine

To calculate:

Distance should leave between the three equal sized posters.

Answer to Problem 18Q

Distance should leave between the three equal sized posters is $1.5ft$

Explanation of Solution

Given information:

  

Calculation:

From the given diagram it is observed that total distance is $15ft$

Distance leave on the both wall side is $3ft$ .

So consider, $x=$ Distance should leave between the three equal sized posters.

So equation become,

  $\begin{array}{l}3+2+x+2+x+2+3=15\\ 2x+12=15\\ 2x=15-12\\ 2x=3\end{array}$

Now divide both sides by $2$ ,

  $\begin{array}{l}\frac{2x}{2}=\frac{3}{2}\\ x=1.5ft\end{array}$

Therefore, Distance should leave between the three equal sized posters is $x=1.5ft$
