To find the height of the rectangle, we need to determine the width of the rectangle first. Looking at the drawing, we can see that the width of the rectangle is 6 cm.
Since the area of the drawing is 78 square centimeters and the rectangle has a width of 6 cm, we can use the formula for the area of a rectangle:
Area = width x height
78 = 6 x height
height = 78 / 6
height = 13
Therefore, the height of the rectangle is 13 cm.
