Answer:
Step-by-step explanation:
here's a somewhat answer, and how to solve it
lets assume that all "60 cm wire is used to make a rectangle"
h = a
w = a + 3
the perimeter of the rectangle is
a + a + a + 3 + a + 3 = 60
4a = 54
a = 13.5
-------------------------------
height = 13.5
width = 16.5
BUT, the problem says "not all the wired is used"
how much? 59? 58? 57.... the lowest value for the shortes side is 1
h = 1
w = 1 + 3 = 4
perimeter : 1 +4 + 4 + 1 = 6cm
