| Since we know that the area of a rectangle is equal to the product of its two measurements, we determine what the width of this rectangle is, for which we divide the area known from the condition of the problem by the length of the rectangle. So, we get:

70/5 = 14 (cm).

Now we will answer the question to the problem and calculate how much the length of the rectangle is greater than its width, for which we subtract the width value from the found length, according to the condition of the problem, equal to 5 cm.Thus, we calculate:

14 – 5 = 9 (cm).

Answer: 9 cm longer.
