What is 15 out of 24 on a quiz in percent is that out of 100

Cross multiply

% x 24 = 15 x 100

Divide by 24 and get the percentage:

% = 15 x 100 / 24 = 62.5 so your answer would be %62.5

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
