Children with expressive language disorder have difficulty conveying or expressing information in speech, writing, sign language or gesture. (For preschool children, the difficulty expressing themselves in writing is not evident, as they have not started formal education.)
Rectangles have longer sides than any type of square. Opposite sides of rectangles are of equal lengths. All sides of squares are of equal lengths. Rectangles have longer sides than any type of square. Opposite sides of rectangles are of equal lengths. All sides of squares are of equal lengths.
The dimensions of the rectangle are found by calculating the distance between various corner points. Recall that we can find the distance between any two points if we know their coordinates. (See Distance between Two Points) So in the figure above: 1  The height of the rectangle is the distance between A and B (or C,D).2  The width is the distance between B and C (or A,D). 3  The length of a diagonals is the distance between opposite corners, say B and D (or A,C since the diagonals are congruent).ut if the sides of the rectangle are parallel to the x and y axes, then the calculations can be a little easier. In the above figure uncheck the rotated box to create this condition and note that: 1  The height is the difference in y-coordinates of any top and bottom point-for example A and B.
