Question

What is the formulor for perimeter

Answer 1

The perimeter is the total distance around the edges of a two-dimensional shape. The formula for calculating the perimeter depends on the shape of the object. Here are formulas for some common shapes:

1. **Rectangle**:
\[
P = 2 \times (length + width)
\]

2. **Square**:
\[
P = 4 \times side
\]

3. **Triangle**:
\[
P = side_1 + side_2 + side_3
\]

4. **Circle (Circumference)**:
\[
P = 2 \pi r
\]
(where \( r \) is the radius)

5. **Parallelogram**:
\[
P = 2 \times (base + height)
\]

6. **Polygon (n sides)**:
\[
P = side_1 + side_2 + ... + side_n
\]

Remember to use the same units for all sides when calculating perimeter!
