# Perimeter of a Trapezoid Formula

The type of polygon that is nothing but a quadrilateral having at least a pair of parallel sides is called Trapezoid. Two sides of a trapezium are parallel. The perpendicular distance between the parallel sides is called the altitude.

The perimeter of a trapezoid formula is given by

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

Where,

a, b, c, d are the lengths of each side.

### Solved Examples

**Question 1: **Trapezoid ABCD has legs 4 cm and 7 cm in length. Its bases are 12 cm and 15 cm respectively. Find the perimeter of the trapezoid.

**Solution:**

Given:

a = 4 cm

b = 7 cm

c = 12 cm

d = 15 cm

Perimeter is given by

p = a + b + c + d

= 4 + 7 + 12 + 15

= 38 cm.
