Answer:
10 sq.in
Step-by-step explanation:
You know the area of a triangle is base*height, then divided by 2.
You can see that the line that is formed after the tip of the triangle is 6, and the rectangle is 11. To find the height, you will then want to subtract 11-6, which is 5.
You can already see that the base is 4, and you just found the height of the triangle is 5.
Using the triangle area formula, it is
4*5/2=10, so in conclusion the answer is 10 sq.in
