a tailor trims 4 feet from opposite edges of a square piece of cloth , and 3 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 - 8 ) * ( x - 6 ) = 120 = 10 * 12 x = 18 the answer is a .
divide(add(add(multiply(const_2, 4), multiply(const_2, 3)), sqrt(add(multiply(const_4, subtract(120, multiply(multiply(const_2, 3), multiply(const_2, 4)))), power(add(multiply(const_2, 4), multiply(const_2, 3)), const_2)))), const_2)
