Santas sleigh travels 300 km/hr how far can he travel in 3 hrs

given :

speed =300km/h

time=3hours

hence distance= speed * time

300*3

900 km

plz mark brainliest

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

i got 10.28 but that rounds up to 10.3
