Karena dipanaskan kawat yang panjangnya 40 cm akan menambah menjadi 52 cm setelah pemanasan. Berapakah panjangnya kawat yang berukuran 72 m?

Yes, it certainly could ! When you first noticed that formula in a book, or when it was given to you in class, did you also notice or learn what it means ?
It means "The sum of all the interior angles in a polygon" = (number of sides - 2) x 180.
Triangle ........ 3 sides ... (3 - 2) = 1 x 180 = 180° degrees ... 60° each if regular Quadrilateral . 4 sides ... (4 - 2) = 2 x 180 = 360° degrees ... 90° each if regular Pentagon ...... 5 sides ... (5 - 2) = 3 x 180 = 540° degrees ... 108° each if regular Hexagon ....... 6 sides ... (6 - 2) = 4 x 180 = 720° degrees ... 120° each if regular Sevenagon ... 7 sides ... (7 - 2) = 5 x 180 = 900° degrees ... 128 and 4/7 each if regular Octagon ........ 8 sides ... (8 - 2) = 6 x 180 = 1080° degrees ... 135° each if regular Nonagon ....... 9 sides ... (9 - 2) = 7 x 180 = 1260° degrees ... 140° each if regular

A regular polygon with interior angles of 140 degrees has 9 sides. This is calculated using the interior angle formula and the sum of interior angles. Hence, the polygon is a nonagon.
