Final answer:
The area of a triangle is obtained using the formula 1/2*base*height. Count the numbers of complete squares on the base and height of your triangle, plug the values into the formula, and calculate the area.
Step-by-step explanation:
The area of a triangle can be obtained using the formula 1/2*base*height, where base and height are the lengths of the base and height of the triangle respectively. In order to apply this formula to your triangle, you need to count the number of complete square units along the base and the height of the triangle on your given grid. Once you have these values, plug them into the formula and calculate the area.
For example, if the base of the triangle on your grid is 5 squares long and the height is 4 squares long, the area of this triangle would be 1/2*5*4 = 10 square units.
