The area of a square can be found using the following formula:
area = (length) x (width)
We know that all sides of the given square are 8 inches in length. Therefore, the length and width must both be 8 inches. Insert any known values into the equation above:
area = (8 in) x (8 in)
Simplify the right side:
area = 64 square inches
We have now proven the area of the square to equal 64 square inches.
To get this, you divide the smaller number by the larger one and get 0.5882... 500 is about 59% of 850, so to find the percent lost, you subtract that from 100 to get 41% decrease
