B. ] Area of square S= 3 ft 6 in. 

 

Answers in square ft. please!  Thanks! 

Answer 1

A.   convert each of L & W to inches, then multiply those two integers to get area in SQ. IN.  Divide by 144 to convert answer to sq ft.

B.   convert side S to 42 inches; (42 in)² = 1764 sq in.  But since 144 sq in = 1 sq ft, divide this answer to get other answer 12.25 sq ft.
