Question

There’s a rectangle with a width of 4 cm and length of 8 cm
P= __cm
A= __cm

Answer 1

To calculate the perimeter (P) and area (A) of the rectangle:

1. **Perimeter (P)** of a rectangle is given by the formula:
\[
P = 2 \times ( \text{length} + \text{width} )
\]
For your rectangle:
- Length = 8 cm
- Width = 4 cm

\[
P = 2 \times (8 \, \text{cm} + 4 \, \text{cm}) = 2 \times 12 \, \text{cm} = 24 \, \text{cm}
\]

2. **Area (A)** of a rectangle is given by the formula:
\[
A = \text{length} \times \text{width}
\]
For your rectangle:
\[
A = 8 \, \text{cm} \times 4 \, \text{cm} = 32 \, \text{cm}^2
\]

So the results are:
- P = 24 cm
- A = 32 cm²
