Answer:
x=−7−√1614,−7+√1614
Step-by-step explanation:
Thats figure is made of 2 triangles and 1 rectangle
so we will find the area of triangles and rectangles then add them
Triangle Area=1/2*x/2*2=x/2
multiply by 2 as we have two triangles=2*x/2=x
Area of a rectangle=x*2=2x
Add them=x+2x=14(given area of trepaziod
3x=14
hope i am correct
I hope I'm not wrong here, but B.1/2? Only because its a 50% chance
