Question 1050990
.
the length of a rectangle is 8 cm less than three times its width. the area is thirteen times the width. find the length and width of the rectangle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
From the condition, you momentarily get length  L = 13.


Then for the width W you have  an equation  L = 3*W-8,  or  13 = 3W -8,
which gives you  3W = 13 + 8 = 21  and  W = {{{21/3}}} = 7.


<U>Answer</U>.  7 and 13.
