Solve the problem. Assume all numbers are approximate unless otherwise stated or the number has been determined by a definition or counting process.If you are told that the height of a trapezoid is 975 mm, that the length of one of its parallel sides is 4423 mm, and that the area of the trapezoid is 3,551,000 mm2, then you could estimate the length of the other parallel side (in mm) by performing the calculation 
. Perform this calculation and report the length found.
A. 7380 mm B. 7000 mm C. 7280 mm D. 7282 mm
