A. 160 square inches
To find the area covered by 4 paving stones, we first need to find the area of one paving stone by calculating the area of the parallelogram. The formula for the area of a parallelogram is base x height.
In this case, the base is 8 inches and the height is 4 inches. So, the area of one paving stone is 8 inches x 4 inches = 32 square inches.
Since there are 4 paving stones, the total area covered by the 4 paving stones is 4 x 32 square inches = 128 square inches.
