you would multiply the Area of a square which is B x H the Area for the square is 0.8 x 0.8 = 0.64
then you multiply the Area of a triangle and the Area of a triangle is B x H divided by 2 and so you multiply the number of triangles there are which is 0.8 x 6 = 4.8 then divide that by 2 which is 2.4 then multiply that with the number of triangles we have all together. there are 4 triangles.
multiply 2.4 x 4 = 9.6 then add the Area of the square which is 0.64 + 9.6 and the answer is 10.24
