**Reiny**, Thursday, December 29, 2011 at 4:21pmlet the length be x

let the width be y

so 2x + 2y < 380

x + y < 190

also x > 110

to graph:

draw a vertical line (dotted) at x = 110

shade in the region to the right of that line

draw the line x+y = 190 , use the intercepts, its easy that way

shade in the region below that line

The region shaded between the two lines and above the x-axis represents your solution. Any point in that region satisfies both conditions.

I suggest using 1 unit on your grid to be 50 ft

**Henry**, Thursday, December 29, 2011 at 5:32pmGiven: L >= 110 Ft., P <= 380 Ft.

P = 2W + 2*110 <= 380,

2W + 220 <= 380,

2W <= 380 - 220,

2W <= 160,

W <= 80 Ft.

2L + 2W <= 380,

Divide both sides by 2:

L + W <= 190,

Let: L = Hor., W = Ver.

L + W <= 10. Scale factor = 19.

Actual values obtained by multiplying by 19.

Graph: L + W = 10, The boundary line.

(L,W).

(0,10) = (0,190)

(10,0) = (190,0).

All points on and below the boundary

line will satisfy the inequality.

Use the coordinates to the rt of = sign for L + W <= 190.
