The sum of the length and width of the rectangle is 14 cm. The length is 4 cm greater than the width. What is the area of this rectangle?

To solve this task, remember that in order to find the area of a rectangle, you need to multiply its length by its width.
Width – a, length – b. Let the width of the rectangle be X, then the length is X + 4.
X + (X + 4) = 14
2X + 4 = 14
2X = 14-4
2X = 10
X = 5
Width – 5 cm, length – X + 4 = 5 + 4 = 9.
Let’s find the area.
S = ab = 5 * 9 = 45 cm ^ 2
Answer: 45 cm ^ 2
