Question

how to find peramiter on a trapazoid

Answer 1

To find the perimeter of a trapezoid, you need to know the lengths of all four sides. The formula for the perimeter (P) of a trapezoid is:

\[
P = a + b + c + d
\]

where:
- \( a \) and \( b \) are the lengths of the two parallel sides (the bases),
- \( c \) and \( d \) are the lengths of the other two non-parallel sides.

### Steps to Calculate the Perimeter:

1. **Measure the Lengths**: Measure or obtain the lengths of all four sides of the trapezoid.
2. **Add the Lengths Together**: Use the formula above to add the lengths of the sides.

### Example:

If a trapezoid has the following side lengths:
- \( a = 5 \) units (one base)
- \( b = 7 \) units (the other base)
- \( c = 4 \) units (one non-parallel side)
- \( d = 3 \) units (the other non-parallel side)

Then the perimeter would be calculated as:

\[
P = a + b + c + d = 5 + 7 + 4 + 3 = 19 \text{ units}
\]

So, the perimeter of this trapezoid would be 19 units.
