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

D) 70 meters²

Step-by-step explanation:

The area of a triangle is able to be found by 1/2*b*h.

The base is 9 - 2 = 7, 7*2 = 14 meters.

The height is 7 - 2 = 5, 5*2 = 10 meters.

Plugging those into the equation gives us 1/2 * 14 * 10.

That is 140/2 = 70 meters².

(The lengths is multiplied by 2 because the key says that each grid is 2 meters long)

5+2x=a
