The height of this triangle is the side at right angles to the pentagon's edge, leading to the center.

The board is made of 9 3×3 boards, and there are 4 colours (red, yellow, green and blue) instead of the basic 2.

Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. [11] X Research source

Playing a match is a common way to play Pentago. Match play consists of playing best out of five games, meaning the first player to win three games wins the match. Then, using the apothem, the area of a regular pentagon will be ½ x apothem x 5. [4] X Research source
