1. Let us calculate what the length of a given rectangle is equal to if it is known that it is 2 3/4 times larger than its width, which is 10 2/5 dm.
10 2/5 * 2 3/4 = 52/5 * 11/4 = (52 * 11) / (5 * 4) = 572/20 = 28 6/10.
2. Next, we calculate the area of this rectangle. To do this, you need to find the product of its two sides.
10 2/5 * 28 6/10 = 52/10 * 286/10 = (52 * 286) / (10 * 10) = 14872/100 = 148 72/100 or 148.72 dm ^ 2.
Answer: The area of the given rectangle is 14872/100 or 148.72 dm ^ 2.
