Answer:
70 m^2
Step-by-step explanation:
The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.
area of triangle = bh/2
area = (14 m)(10 m)/2
area = 140 m^2/2
area = 70 m^2
