<PRE><B>Question 223776</B>
find the dimensions of the rectangle meeting the specified conditions
the perimeter is 320 cm and the width is 20 cm less than the length
----------------------
Perimeter = 2(L + W)
320 = 2(L + (L-20))
160 = 2L-20
2L = 180
L = 90 cm (length)
W = L-20 = 70 cm (width)
