Can someone help me…7th grade math

Answer:6 square units
Step-by-step explanation:
We're looking at the triangle inside the rectangle not the rectangle.
The length of I to H as the length is 3 units.
The width of H to G is is 4 units.
4x3=12 12/2=6
6 square units
We divide by 2 since the area of a triangle is (length x width)/2
Hope this helps
