The area of the rectangle is 40 cm2, its width is 5 cm. The length of the rectangle is calculated.

To solve this problem, recall the formula for the area of a rectangle. The area of the rectangle is equal to the product of the length and the width. S = a * b, where a is the length and b is the width. Knowing that the area of the rectangle is 40 square centimeters, and its width is 5 centimeters, we calculate the length of the rectangle.
a = 40/5 = 8 cm.
Answer: 8 cm.
