The perimeter of a rectangle is 36 cm. If it is 12 cm long, find it's width

Answer 1

To find the width of the rectangle, we first need to know the formula for the perimeter of a rectangle:

Perimeter = 2(length + width)

Given that the perimeter of the rectangle is 36 cm and the length is 12 cm, we can substitute these values into the formula and solve for the width:

36 = 2(12 + width)
36 = 24 + 2w
12 = 2w
width = 6 cm

Therefore, the width of the rectangle is 6 cm.
