solve: the perimeter of a certain rectangle is 16 times the width.
The length is 12 cm more than the width.
Find the width of the rectangle.
:
Let x = the width
then
(x+12) = the length
and
16x = the perimeter
:
the perimeter equation:
2(x+12) + 2x = 16x
2x + 24 + 2x = 16x
4x + 24 = 16x
24 = 16x - 4x
24 = 12x
x = 24%2F12
x = 2 cm is the width
:
:
Check solution using the perimeter (14cm = the length
2(14) + 2(2) = 16(2)
28 + 4 = 32
