Question

a rectangle has a 12 meter length and a width of 400 cm. what is the perimeter, in cm, of the rectangle

Answer 1

To find the perimeter of the rectangle, we use the formula for the perimeter \( P \):

\[
P = 2 \times (length + width)
\]

First, we need to convert the length from meters to centimeters. We know that:

\[
1 \text{ meter} = 100 \text{ centimeters}
\]

So, the length of the rectangle in centimeters is:

\[
12 \text{ m} = 12 \times 100 = 1200 \text{ cm}
\]

The width is already given in centimeters:

\[
400 \text{ cm}
\]

Now we can calculate the perimeter:

\[
P = 2 \times (1200 \text{ cm} + 400 \text{ cm})
\]
\[
P = 2 \times (1600 \text{ cm})
\]
\[
P = 3200 \text{ cm}
\]

Therefore, the perimeter of the rectangle is \( 3200 \) cm.
