Question 1046383
.
A rectangular room is 3 meters longer than it is wide, and its perimeter is 22 meters. Find the dimension of the room. 
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let W be the width, in meters.
Then the length is W+3 meters.

For the perimeter, you have then

W + (W+3) + W + (W+3) = 22,  or

4W + 6 = 22,  or

4W = 22 - 6,

4W = 16,

W = {{{16/4}}} = 4.

Thus the width is 4 meters.

Then the length is 4 + 3 = 7 m.
</pre>

Solved.
