It takes 52 minutes for 5 people to paint 5 walls.
how many minutes does it take 20 people to paint 20 walls?
answer as soon as (you get 20 points if you answer! )

-- 5 people paint 5 walls in 52 minutes.

-- 5 people paint 1 wall in (52/5) minutes

-- 1 person could paint 1 wall in (5)x(52/5) = 52 minutes

-- 1 person could paint 20 walls in (52 x 20) = 1,040 minutes

-- 20 people could paint 20 walls in (1,040/20) = 52 minutes

An easier way:

-- 5 people paint 5 walls in 52 minutes

-- If there are 20 walls, that's 4 times as much work.  If you put 4 times as many people on the job, they can get it done in the same amount of time . . . . . 52 minutes.

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

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
