The perimeter of the rectangle is 9.6 m, its length is 1.4 times its width. Find the area of this rectangle?

1. If we imagine that the width is equal to about, then the length is equal to 1.4o. By increasing the sum of the length and width by 2 times, we get the value of the perimeter of the rectangle, we solve the resulting equation:
2 * (o + 1.4o) = 9.6,
2о + 2.8о = 9.6,
4.8o = 9.6,
o = 9.6 / 4.8,
o = 2.
2. Find the length:
2 * 1.4 = 2.8.
3. Find the product of the length and width of the rectangle, get its area:
2.8 * 2 = 5.6 m2.
Answer: the area of the rectangle is 5.6 m2.
