# The formula for the area of a trapezoid

Legend:

## P – trapezoidal area

## a – length of the upper side of the trapezoid

## b – length of the trapezoid base

## h – the length of the height lowered to the side b

Sample task:

Calculate the area of the trapezoid with the base b = 6.5 cm, side a = 5.5 cm and height h = 2.5 cm

The area of the trapezoid with the base b = 6.5 cm and the side a = 5.5 cm and height h = 2.5 cm, is 15cm²
