<PRE><B>Question 1196633</B>
&lt;br&gt;
The perimeter is 50, so length plus width is 25.&lt;br&gt;
x = width
25-x = length&lt;br&gt;
The area is 150:&lt;br&gt;
x(25-x)=150
25x-x^2=150
x^2-25x=-150
x^2-25x+150=0
(x-15)(x-10)=0&lt;br&gt;
ANSWER: The dimensions of the notebook are 10cm and 15cm.&lt;br&gt;
