Answer
Largest possible area: 11,100 $cm^2$
Smallest possible area: 9,800 $cm^2$
Work Step by Step
Area of a rectangle = height $\times$ width
Step 1:
To find the largest possible area of the rectangular window use the given largest possible dimensions for height (150 cm), and width (74 cm).
150 cm $\times$ 74 cm = 11,100 $cm^2$
Step 2:
Repeat for smallest possible dimensions (140 cm and 70 cm) to find smallest possible area.
140 cm $\times$ 70 cm = 9,800 $cm^2$
