Homework Help: math

Posted by help me plz on Tuesday, May 8, 2007 at 9:11pm.

the length of a rectangle is 6 cm more than its width. the area is 11 cm squared. find the length and width.



look at the post by anonymous at 8:55, it is almost the same as yours.
Do it the same way.

length= x+6
width=x

x(x+6)=11
x^2 + ^x =11
x^2+6x-11=0
(x-_)(x-_)

solve for x.

Then substute the x for the length and width.
