Answer:
90 m
Step-by-step explanation:
The piece on the right side fits perfectly in the left side so you can move the triangle to the left in order to make a square. After that, you can do 10 times 9 because 5+4=9 to get 90m as the area.
90 m^2
The area of a rectangle that is 5m by 10m is 50 m^2.
the parallelogram that has a height of 4m and the base length of 10m is 40 m^2.
40 + 50 = 90
