The length of the rectangle is 28 cm and the width is seven times shorter, find the area of the rectangle.

Given: Rectangle; the length of the rectangle is 28 cm; width 7 times shorter than its length.
Find: Area of a rectangle.
Let’s use the formula for the area (S) of a rectangle through its sides (a and b are length and width): S = a * b.
Known length: a = 28 cm.
First, find the width b. According to the condition of the task, b = a: 7. Therefore, b = 28 cm: 7 = 4 cm.
Therefore, S = a * b = (28 cm) * (4 cm) = (28 * 4) cm2 = 112 cm2.
Answer: The area of the rectangle is 112 cm2.
