To find the area of a complex shape:

⇒ must cut the whole shape into a simpler shape

  • square with side lengths of 4 in
  • 2 triangles with a base of 4 in. and a height of 8 in.
  • 2 triangles with a base of 4 in. and a height of 10 in.

Let's calculate:

  • Area of 2 triangles with a base of 4 in. and a height of 8 in.


Area = (1)/(2)*4*8 + (1)/(2)*4*8=16+16=32\\

  • 2 triangles with a base of 4 in. and a height of 10 in.


Area = (1)/(2)*4*10 + (1)/(2)*4*10=20+20=40

  • square with side lengths of 4 in


Area = 4 * 4=16

Total Area: 32 + 40 + 16 = 88 in²

Answer: 88 in²

Hope that helps!
