Use the product rule to simplify the radical— square root 315

Using the product rule, simplify the radical as such:

√315 = √7 × √45 = √7 × √9 × √5 = 3 × √7 × √5 = 3√35

The simplified radical of √315 is 3√35.

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

don't know what that says sorry i can't you
