Front

How do you convert feet and inches to square feet?

Back

To convert feet and inches to square feet, first convert the entire measurement to feet (e.g., 12 ft 4 in = 12 + 4/12 = 12.33 ft), then calculate the area.

Front

What is the area of a shaded region in geometry?

Back

The area of a shaded region is found by subtracting the area of the unshaded part from the total area of the figure.

Front

What is the relationship between area and units of measurement?

Back

Area is measured in square units (e.g., cm², in², ft²), which represent the two-dimensional space occupied by a shape.
