Answer:
105 cm squared
Step-by-step explanation:
15 × 6 to get the rectangle = 90
Now we have a triangle left so you do 15 - 9 for the base which equals = 6 and multiply that by hight (6×5=30) and since it's a triangle and not a square we have to divide that answer by 2 and we get 15, and once we add those together, we get 105. (I really hope that help!!)
