Question 1210163
<br>
The figure APPEARS to be a kite plus a triangle.  But there is nothing in either your written question or on the referenced figure that tells us so.<br>
We don't even know whether the two segments that APPEAR to be perpendicular to each other in fact are perpendicular.<br>
Without a description of the figure in your text or on the figure, we would only be guessing at the answer.<br>
Re-post, defining the problem clearly.<br>
------------------------------------------------------------------------<br>
Tutor Edwin has solved the problem assuming that the part of the figure that looks like a kite is in fact a kite.  Before the trapezoid was added, the area of the composite figure was 132.<br>
When the trapezoid is added, Edwin uses a clever way of finding the area of the trapezoid by dividing it into 3 congruent triangles.<br>
The area of the trapezoid is found more easily using the standard formula for the area of a trapezoid: height times average of the bases.  In this problem that is<br>
{{{(8)((24+12)/2)=(8)(18)=144}}}<br>
And then the total area of the new composite figure is 132+144 = 276.<br>
