Question 249967
The formula for the area of a rectangle is A=l*w.

So, the area is 3.5*4.5 = 15.75 meters.

You are asked to express your answer in inches. Presumably, your teacher or your textbook contains a factor that converts meters to inches.  THe conversion factor to two decimal places is 1 meter = 39.37 inches.  Check to see if you were given a different conversion factor.

15.75 meters * 39.37 inches per meter = 620.078 inches.
