A rectangular section of land made up of wheat farms has a length of 5 x 10 meters and a width of 7 x 10% meters. What is the area of the land in square meters?

i don’t see a picture

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
