Answer:
A = 17.5 sq meters
Step-by-step explanation:
First, find the measurements of the triangle labeled 2.
The bigger shape is a rectangle, which means we can figure how big the triangle is.
You want to do 9m - 4m because the 4m isn't included in the triangle. Do the same with 12m - 5m.
So, your triangle has a height of 5m and a base length of 7m.
Now, use the formula for the area of a triangle: [tex]\frac{1}{2}[/tex](base*height)
A = [tex]\frac{1}{2}[/tex](7*5)
A = [tex]\frac{1}{2}[/tex](35)
A = 17.5 sq meters
