[6th Grade Math - Area]

Trying to help my daughter with her homework. Teacher and I got very different answers. Please help

Need to find the area of the composite shape. Her teacher says the area 33.75cm squared (or so my daughter claims). I got a vastly different answer. 330.75. Brackets the shape into 4 small rectangles and a large square. Found the area for each shape and added. Got an area of 55.125 for each rectangle and 110.25 for the area of the square. Who’s right or are we both wrong?
