Step-by-step explanation:

Convert to Scientific Notation

8.6 × 10^8

₋₋₋₋₋₋₋₋₋₋₋₋

3.2 × 10^3

Convert the fraction to a decimal by dividing the numerator by the denominator.

268750

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the e xponent will be positive.

2.6875 × 10^5

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
