You can put this solution on YOUR website! What is the area of the trapezoid with lower base of 12 cm, upper base of 8 cm if a leg 4 cm long makes an angle of 60 degrees with the lower base?
:
Area of trapezoid: A =
where
a = 12
b = 8
we have to find h
We can use the sine of 60 to find h
sin(60) =
.866 =
h = .866 * 4
h = 3.46 cm
:
A =
A =
A =
A = 34.64 sq/cm

Hope this made your Christmas Merry!
