Answer 3

Calculating the Area of a Rectangle

To calculate the area of a rectangle, you can use the formula: Area = Length x Width.

Given: - Length = 40 mm - Width = 3 cm

First, we need to ensure that the units are consistent. Let's convert the width to millimeters.

Conversion of Width to Millimeters

1 cm = 10 mm So, 3 cm = 3 * 10 mm = 30 mm

Now, we can calculate the area using the formula.

Calculating the Area

Area = Length x Width Area = 40 mm x 30 mm Area = 1200 square millimeters

Therefore, the area of the rectangle is 1200 square millimeters.
