A rectangle is to be drawn with perimeter 64 cm. If the length is to be 14 cm more than the width, determine the area of the rectangle.

If I let x=length, y=width then would it be x=y+14 and y=x-1? or no?

is this your given?

anonymous · Answer

do you want me to plug them in or do you know how

anonymous · Answer

Plug L=w+14 into 2L+2W=64

anonymous · Answer

2L+2W=P
2(14)+2y=64
28+2y=64
-28       -28
2y=36
/       /
2       2
y=18

A=14 * 18
A=252??
I know that the answer is wrong cause the back of the book says 207 cm^2. What step did I make a mistake?
