Answer:
103.58
Step-by-step explanation:
Find the total area of the shape
L*W=A
8*13=104m
Find the area of the triangle, since the top of the shape is 13m then the bottom is also 13m.
4+4=8
13-8=5
So the base of the triangle cutout is 5m
Now find the area of the triangle. The formula for this is:
A=1/2 * base/height
A=1/2 * 5/6
A of triangle= 5/12m
104 - 5/12 =103.58m
