what is the area to this trapezoid.

Question

Answer 1

If we put height from vertex above we get triangle, were one leg is 3cm and altitude of trapezoid is 3√3 cm

Lower base is 10 + 6 = 16 cm

So area a = (10 + 16)3√3/2 = 39√3 cm².

Answer 2

Drop a perpendicular from one corner of the upper base.

A 30-60-90 triangle is formed.

The height (side opposite the 60° angle) is 3√3
