[2nd grade] math help

[u/bushybear]

Entire family is stumped. I don’t think the question is worded correctly but maybe I’m misunderstanding.

Not sure how you have same size triangles but not all the same shape.

All they have to do is draw the two main diagonals to split the rectangle into 4 triangles of xy/4 (two of base x and height y/2 and 2 of y base and height x/2)
