The length of a rectangular boat storage shed must be 4 meters more than the width, and the perimeter must be at least 124 meters. What is the range of the values for yhe width.
.
Let w = width of rectangular storage
then
w+4 = length
.
perimeter = 2(length + width)
we now have:
124 <= 2((w+4) + w)
124 <= 2(w+4+w)
124 <= 2(2w+4)
124 <= 4w+8
116 <= 4w
29 meters <= w
.
This says w "greater than or equal" to 29 meters
or
At least 29 meters
