Answer 1

To find the area of the rectangle, we first need to determine its dimensions.

1. The height (h) of the rectangle is given as 5 centimeters.
2. The length (l) of the rectangle is twice its height, so:
\[
l = 2 \times h = 2 \times 5 \text{ cm} = 10 \text{ cm}
\]

Now that we have the height and length, we can calculate the area (A) of the rectangle using the formula:
\[
A = l \times h
\]
Substituting the values we have:
\[
A = 10 \text{ cm} \times 5 \text{ cm} = 50 \text{ cm}^2
\]

So the area of the rectangle is **50 cm²**.
