Answer 3

Problem Statement

You have a rectangle with a width of 8 cm, and the length is 12 times larger than the width. You need to find the area and perimeter of the rectangle.

Solution

To find the area and perimeter of a rectangle, we can use the following formulas:

- Area of a rectangle: A = length × width - Perimeter of a rectangle: P = 2 × (length + width)

Given that the width of the rectangle is 8 cm and the length is 12 times larger than the width, we can calculate the length as follows:

Length = 12 × Width = 12 × 8 cm = 96 cm

Now, let's calculate the area and perimeter of the rectangle using the formulas mentioned above.

Calculation

1. Area of the rectangle: - Length = 96 cm - Width = 8 cm - A = Length × Width = 96 cm × 8 cm = 768 cm² 2. Perimeter of the rectangle: - Length = 96 cm - Width = 8 cm - P = 2 × (Length + Width) = 2 × (96 cm + 8 cm) = 2 × 104 cm = 208 cm

Answer

Therefore, the area of the rectangle is 768 cm² and the perimeter is 208 cm.
