The perimeter of a rectangle is 28cm.Find the area of the rectangle if the breadth is 4cm?

To find the area of a rectangle, we need both the length and the breadth (width). However, in your question, only the breadth is given (4 cm), and the perimeter is provided as 28 cm. With this information, we can find the length of the rectangle. The formula for the perimeter of a rectangle is: Perimeter = 2 * (Length + Breadth) Given that the perimeter is 28 cm and the breadth is 4 cm, we can substitute these values into the formula and solve for the length: 28 = 2 * (Length + 4) 28 = 2 * Length + 8 2 * Length = 28 - 8 2 * Length = 20 Length = 20 / 2 Length = 10 cm Now that we know the length (10 cm) and the breadth (4 cm), we can calculate the area of the rectangle: Area = Length * Breadth Area = 10 cm * 4 cm Area = 40 cm² Therefore, the area of the rectangle is 40 square centimeters.
