Answer:
105 square feet
Step-by-step explanation:
First of all, find the area of the rectangle (length x width). 7*12 = 84. Now, find the area of the triangle [(base x height)/2]. 6*7 = 42. 42/2 = 21.
Add both of these areas together: 84 + 21 = 105. The area is 105 square feet.
<h3>x less than or equal to 5</h3>
