John Roy creates this drawing a composite shape for an art contest. The area of the drawing is 78 square centimeters. What is the height of the rectangle?
a. 12 cm
b. 13 cm
c. 10 cm
d. 8 cm
To find the height of the rectangle, we need to divide the total area by the length of the rectangle.
Area = Length x Height
78 = Length x Height
Length = 8 cm
Height = 78 / 8 = 9.75 cm
Therefore, the height of the rectangle is closest to 10 cm, so the answer is:
c. 10 cm
