Where <em>b</em> is the base and <em>h</em> is the height of the triangle.
2. Then, when you substitute the values given in the problem you obtain:

3. You know that the shape is made of 12 right triangle of equal size, therefore, multiply the area obtained by 12.
4. Then the area of the shape is:

Step-by-step explanation:
=n2-11n+18
=n2-(9+2)n+18
=n2-9n-2n+18
=n(n-9)-2(n-9)
=(n-2)(n-9)
