Answer: area = 78 square units
======================================
Explanation:
Rotate the arrow so that it is pointing up.
Draw a line separating the arrow into a triangle up top and a rectangle below that.
The rectangular portion has area of 6*4 = 24 square units.
-----------------
The triangular portion up to has area of
0.5*(base)*(height) = 0.5*(4+4+4)*(15-6) = 54
The base is 4+4+4 due to the '4's along the bottom of the triangle. The middle 4 might be the trickiest to spot, but keep in mind that rectangles have opposite sides that are the same length.
The height of the triangle is 15-6 since we start with an overall height of 15, and then subtract off 6 (which was the height of the rectangle).
-----------------
Once you know the areas of the triangle and rectangle, you add them up to get 54+24 = 78 square units.
The value 14 along the diagonal portions of the triangle isn't used. This information is probably put in to distract or trick students. However, if you needed to find the perimeter, then you will use the 14's.
