What is the actual area, in square meters, of this field?

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
