The perimeter of a rectangle is 36cm, if it is 11.2 long find the width

1 answer

Let the width of the rectangle be w.

From the given information:

Perimeter = 2(length + width)
36 = 2(11.2 + w)
36 = 22.4 + 2w

Subtracting 22.4 from both sides:
36 - 22.4 = 2w
13.6 = 2w

Dividing by 2:
w = 6.8

Therefore, the width of the rectangle is 6.8 cm.
