**helper**, Thursday, January 27, 2011 at 9:41pmPerimeter ABCD = 54

L = 12 in

Perimeter LMNO = x

L = 2.4 ft = 28.8 in

P = 2w + 2L

Use Ratio to find x (perimeter LMNO)

12/28.8 = 54/x

Cross multiply

12x = 1555.2

x = 129.6

LMNO P = 129.6

L = 28.8

P = 2w + 2L

129.6 = 2w + 2(28.8)

Solve for w, width of LMNO
