Answer: 134.28
Step-by-step explanation: (I know you said not to, but imma do it anyways)
How to find the area of a triangle: base times height divided by 2
The equation will be 6.8 times 6.4 divided by 2 = 21.76
This is the area of one triangle, there is 4 triangles
(6.8 from get this length from the square which has all four sides the same length)
There are 4 triangles, so times 21.76 by 4, to get 88.04
fianally, you get the area of a square by doing length times height
6.8 times 6.8 = 46.24
then all all the area together. 88.04+46.24=134.28
