Answer:
the area of the shaded region is 119.5
Step-by-step explanation:
area of a triangle formula 1/2bh (b= base) (h=height)
area of big triangle work
1/(20)(18)
20x18= 360
360 divided by 2 is 180 area of big triangle is 180
moving on to smaller triangle
1/2bh
1/2(11)(11)
121/2
60.5
THEN you subtract using bigger triangle by smaller
180-60.5=119.5
Yes because you will still be able to get a Number that will verify.
