Explanation:

The best version of the given sentence is version B. There are two mistakes in the original sentence:

The highlighted commas should be omitted. When only two things are listed and connected by a coordinating conjunction such as and, the conjunction shouldn't be preceded by a comma.

The only comma that should be used in the sentence is the one before but. But is a coordinating conjunction. When coordinating conjunctions are used to connect two independent clauses, like in this case, they should always be preceded by a comma.

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172
