# ISO trapezium

Calculate area of isosceles trapezoid with base 95 long, leg 27 long and with the angle between the base and leg 70 degrees.

Result

S =  2176.02

#### Solution:

$a = 95 \ \\ v = 27 \cdot \sin 70 ^\circ = 25.37 \ \\ c = a-2a \cos 70 ^\circ = 30.02 \ \\ \ \\ S = \dfrac{a+c}{2} v = \dfrac{ 95+30.02 }{2} \cdot 25.37 = 2176.02$
