One board is 6 feet long and the other is 5 1/2 feet long. the total area os 60 3/8 sq ft. what is the width?

5 1/4 ft

Step-by-step explanation:

... Area = length × width

Dividing by length, we find width to be ...

... width = Area / length

... = (60 3/8 ft²)/(6 ft +5 1/2 ft) . . . . total length is the sum of the 2 board lengths

... = (483/8 ft²)/(92/8 ft) = 483/92 ft = 5 1/4 ft
