Answer:
144.5cm²
Step-by-step explanation:
Think of this as 2 different shapes, the triangle and the rectangle. Adding these 2 areas together gives you the total area.
A rectangle's area is given by a=lw.
By substituting in the values, you get a=13*9. This can be solved to a=117cm² for the rectangle.
A triangle's area is given by a=[tex]\frac{bh}{2}[/tex].
By substituting in the values, you get a=[tex]\frac{5*11}{2}[/tex] or [tex]\frac{55}{2}[/tex], which can be solved to a=27.5cm² for the triangle.
Adding the 2 together gives the total area.
a=117+27.5, which gives 144.5cm².
