Answer 2

Calculation of the Rectangle's Area

To calculate the area of a rectangle, we need to know its width and length. In this case, the width of the rectangle is given as 8 cm, and the length is 4 times greater than the width.

Let's calculate the length of the rectangle first. Since the length is 4 times greater than the width, we can multiply the width by 4:

Length = 8 cm * 4 = 32 cm

Now that we have the width and length of the rectangle, we can calculate its area. The area of a rectangle is given by the formula:

Area = Width * Length

Substituting the values we have:

Area = 8 cm * 32 cm = 256 cm²

Therefore, the area of the rectangle is 256 cm².
