As an architect, you are designing a new house. a window has a height between  150  cm   and  160  cm and a width between  82  cm   and  70  cm   .when calculating the areas what is the appropriate number of significant figures

We can write the statement above using inequalities. Let's name:

x: The height of a window (in cm)
y: The width of a window (in cm)

Then writing those statements as equations:





So the area is given by the equation:

in



So there are a variety of figures we can choose as long as the area is between and
