Answer 2

Problem Analysis

We are given that the length of a figure is 65 cm, and the width is 3 times the length. We need to find the perimeter and area of the figure.

Calculation

Let's calculate the width of the figure first. Since the width is 3 times the length, we can calculate it as follows:

Width = 3 * Length = 3 * 65 cm = 195 cm

Now that we have the length and width, we can calculate the perimeter and area of the figure.

Perimeter

The perimeter of a figure is the sum of all its sides. In this case, the figure has two sides of length 65 cm and two sides of length 195 cm. Therefore, the perimeter can be calculated as:

Perimeter = 2 * Length + 2 * Width = 2 * 65 cm + 2 * 195 cm = 390 cm + 390 cm = 780 cm

So, the perimeter of the figure is 780 cm.

Area

The area of a figure is the measure of the region enclosed by its sides. In this case, the figure is a rectangle, and the area can be calculated as the product of its length and width. Therefore, the area can be calculated as:

Area = Length * Width = 65 cm * 195 cm = 12675 cm^2

So, the area of the figure is 12675 cm^2.

Conclusion

The perimeter of the figure is 780 cm and the area is 12675 cm^2.
