The length of a rectangular label is 2.5 cm less than twice the width.
The perimeter is 40.6 cm. Find the width.
:
Perimeter: 2L + 2W = 40.6
:
It says,"length is 2.5 cm less than twice the width."
L = (2W-2.5)
:
In the perimeter equation, replace L with (2W-2.5)
2(2W-2.5) + 2W = 40.6
4W - 5 + 2W = 40.6
6W = 40.6 + 5
6W = 45.6
W =
W = 7.6 cm is the width
:
I'll let you find the Length, find the perimeter using these values to check it.
