The perimeter of the rectangle is 10dm 6cm. The width of the rectangle is 2 dm. What is the length of this rectangle?

We know that the perimeter of a rectangle is the sum of twice its length and twice its width. We find out what the doubled width of the rectangle is, if we know that its width is 2 dm.

2 * 2 = 4 dm.

Now we find out what the doubled length of this rectangle will be if we know that its perimeter is 10 dm 6 cm.

10.6 – 4 = 6.6 dm.

Now let’s calculate what the length of the given rectangle is equal to.

6.6 / 2 = 3.3 dm or 3 dm 3 cm.

Answer: The length of the given rectangle is 3 dm 3 cm.
