If the jet propulsion laboratory has a photograph of the mars rover measuring 1.5 meters by 2 meters, how
many square inches does the photograph contain?

  about 4650 square inches

Step-by-step explanation:

The area is the product of length and width. Each conversion factor cancels a unit we don't want and replaces it with a unit we do want.

  (1.5 m)(2 m)((1 in)/(0.0254 m))^2 = 3/.00064516 in^2 = 4650.0093... in^2

  ≈ 4650 in^2

The photograph has an area of 4650 square inches.
