Second number line

Step-by-step explanation:

Intervals in the Number Line

When representing real intervals in the number line, we use solid lines that start from the lower or upper limit and end in the final number. If there is no limit, then we use an arrow pointing to plus or minus infinity.

If the endpoint is included in the interval, we place a filled circle, if it's not included, we use a hollow circle.

We want to show the interval , this means we must include the 11 and go up to positive infinity. The only number line with such characteristics is that on the second option.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

unless if u could do my questions, if not i wouldn't want to
