Jennifer says that the figure below has an area of 4 square feet. Is she right?
An 8 by 7 array of squares has a shaded triangle that covers 2 whole squares, most of 2 other squares, about half of 2 other squares, and a small amount of 2 other squares. One square equals 1 square meter.
Part A
Is Jennifer correct about the number of units? Drag the words to explain your answer. Words may be used once, more than once, or not at all.
No Yes are no There.
gaps if Jennifer uses 4 squares.
No, Jennifer is not correct about the number of units. There are gaps if Jennifer uses 4 squares.
To determine if Jennifer is correct about the area of the figure, we need to calculate the total number of squares.
The figure is described as an 8 by 7 array of squares. This means there are 8 rows and 7 columns of squares, resulting in a total of 8 x 7 = 56 squares.
However, Jennifer states that there are 4 squares in total. This contradicts the actual count of 56 squares in the figure.
Therefore, Jennifer is not correct about the number of units (squares). The correct answer to the question is "No."
