# Trapezoid MO

The rectangular trapezoid ABCD with the right angle at point B, |AC| = 12, |CD| = 8, diagonals are perpendicular to each other.

Calculate the perimeter and area of ​​the trapezoid.

Correct result:

p =  33.31
A =  69.25

#### Solution:

$A=\frac{\left(\mathrm{\mid }AB\mathrm{\mid }+\mathrm{\mid }CD\mathrm{\mid }\right)\cdot \mathrm{\mid }BC\mathrm{\mid }}{2}=69.25$
