a tailor trims 6 feet from opposite edges of a square piece of cloth , and 5 feet from the other two edges . if 120 square feet of cloth remain , what was the length of a side of the original piece of cloth ?
"let the original side of the square be x . ( x - 12 ) * ( x - 10 ) = 120 = 10 * 12 x = 22 the answer is b ."
divide(add(add(multiply(const_2, 6), multiply(const_2, 5)), sqrt(add(multiply(6, subtract(120, multiply(multiply(const_2, 5), multiply(const_2, 6)))), power(add(multiply(const_2, 6), multiply(const_2, 5)), const_2)))), const_2)
