Calculate them separately and add them together.
The formula for the area of a triangle is [tex]a= \frac{1}{2}b*h [/tex]
[tex] \frac{1}{2} (6ft)*2ft=6ft^2[/tex] is the area of the triangle.
The area of a rectangle is [tex]a=b*h[/tex]
[tex]5ft*6ft=30ft^2[/tex] is the area of the rectangle.
[tex]30ft^2+6ft^2=36ft^2[/tex] is the total area.
