okay guys, just one more word problem. and i don't think this one has any typos in it:

The perimeter of a rectangle is 27 cm and its area is 35 square centimeters. Find the length and the wide of the rectangle.

i just need help getting it started...

Ok P=27cm where P is the perimeter. A = 35cm^2 where A is the area.

We know that A =L*W and P=2(L+W) thus we have

(1) 35=L*W

(2) 27=2(L+W)

From (1) we have 35/L = W. Use this in (2) to get

27=2(L + 35/L) Now solve for L. This is a quadratic equation.

thanks a lot. i had been trying to do this for a long time :)

y=x(x-10)

x=0

x-10=0

solutions=0 and 10
