Find the missing length of the triangle.

b = 24

Step-by-step explanation:

you are going to use the pythagorean theorem. you know b (a short side) and c (the hypotenuse), so fill those values in and change the variable to match that of the problem. so now you are going to solve these. . now you subtract 100 from both sides to get b on one side and the numbers on the other. . now take the square root of both sides because you want just b. . which equals b= 24. that's how you get the answer.

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
