<PRE><B>Question 1043944</B>
a problem where the perimeter and area of a rectangle are the same. The width of the rectangle is 3 and the length is x. I need to write an equation to solve for x to get the area and perimeter.
:
Area = perimeter
L*W = 2L + 2W
Given that W=3
3L = 2L + 2(3)
3L - 2L = 6
L = 6 is the length
See if that checks out
3*6 = 2(6) + 2(3)
18 = 12 + 6</PRE>
