(1 point)
A. 10 centimeters
B. 13 centimeters
C. 12 centimeters
D. 8 centimeters
B. 13 centimeters
To find the height of the rectangle, we can use the formula for the area of a rectangle:
Area = base x height
Since the top and bottom sides of the shape are both 6cm, the base of the rectangle is 6cm. We are given that the area of the drawing is 78 square centimeters. Therefore:
78 = 6 x height
height = 78 / 6
height = 13
So, the height of the rectangle is 13 centimeters.
