Answer 3

Drawing a Rectangle with Equal Perimeter

To draw a rectangle with a perimeter equal to the perimeter of a quadrilateral with sides of length 8 cm, 6 cm, 8 cm, and 9 cm, we can follow these steps:

1. Calculate the Perimeter of the Quadrilateral: - The perimeter of the quadrilateral is the sum of its four sides. - Perimeter = 8 cm + 6 cm + 8 cm + 9 cm = 31 cm.

2. Divide the Perimeter by 2: - Since a rectangle has two pairs of equal sides, we can divide the perimeter of the quadrilateral by 2 to get the length of each pair of equal sides for the rectangle. - Perimeter of the rectangle = 31 cm / 2 = 15.5 cm.

3. Draw the Rectangle: - Using a ruler and a pencil, draw a rectangle with two pairs of equal sides, each measuring 15.5 cm.

Calculating the Area of the Rectangle

To calculate the area of the rectangle with the sides we've drawn, we can use the formula:

Area = length * width

In this case, the length and width of the rectangle are both 15.5 cm (as calculated from the perimeter of the quadrilateral).

Area = 15.5 cm * 15.5 cm = 240.25 cm^2

Therefore, the area of the rectangle is 240.25 square centimeters.

This process ensures that the rectangle has a perimeter equal to the given quadrilateral and provides the area of the resulting rectangle.
