Question: 1 / 400

What is the area of a rectangle with a length of 10 cm and a width of 4 cm?

20 cm²

30 cm²

40 cm²

To find the area of a rectangle, the formula used is:

\[ \text{Area} = \text{Length} \times \text{Width} \]

In this case, the length of the rectangle is given as 10 cm, and the width is 4 cm. Plugging these values into the formula provides:

\[ \text{Area} = 10 \, \text{cm} \times 4 \, \text{cm} = 40 \, \text{cm}^2 \]

Thus, the area of the rectangle is 40 cm². Understanding this formula and how to apply it is critical for solving questions related to the areas of rectangles, which are common in various mathematics contexts. Each term in the multiplication represents a fundamental measurement of the rectangle, and their product gives the total space enclosed within the rectangle's boundaries.
