| Answer: the width of the rectangle is 2 times less than the length.
Let’s translate the area of a rectangle from dm² to m ². To do this, consider a 1 m² square.
The side length of this square will be 1 m or 10 dm. We calculate the area in dm² by multiplying the side length in dm by itself:
10 * 10 = 100 dm².
1 m² = 100 dm².
Means:
7200 dm² = 7200/100 = 72 m².
If we divide the area value by the length of one of the sides, then we find out the length of the second side:
72/6 = 12 m.
The larger side of the rectangle is usually called the length, the smaller – the width.
We divide the larger value of the side length by the smaller one and get the answer to the problem question:
12/6 = 2.
