Geometry

You need to find the area of the square first.

8x8=64un^2

Then you must find the area for the four triangles.

8x6=42un^2

42un^2/2=21un^2

Then multiply this by four to find the area of all the triangles.

21un^2x4=84un^2

Then add the areas of the triangles and squares.

84un^2+64un^2=148un^2
