Alex simplified the expression 7+(3x 1.4)+5+2+(5x1.4) to find the area of the figure on the grid. What error did Alex make?
He found the perimeter of the figure instead of the area.
He added the lengths of the lines creating the indentation instead of subtracting them.
He used 5x1.4 and 3 x 1.4 as the length of each diagonal line instead of 5 and 3.
He added the five lengths together instead of multiplying them.
