Suppose the length of the rectangle is a. Then the width of the rectangle will be 5 / 7a. Thus, the area of the rectangle will be equal to 5/7 a * a, which is equal to 35 dm² by condition. We get that
a² = 7/5 * 35dm² ie.
a² = 49 dm², which means
a = 7dm – the length of the rectangle.
the width of the rectangle is 5/7a = 5/7 * 7dm = 5dm.
