A rectangular flower bed is 14 feet long and 16 feet wide. Rose bushes cover 75 percent of the area of the flower bed. How many square feet is planted in a rose bush

Step-by-step explanation:

First we need to fin the area of the rectangular flower bed:

and we know that the length is:

and the width:

so the total area is:

Since 75% of the area is covered with rose bushes, we need to find how much is 75% out of the .

To find this percentage, we divide the total area by 100, and multiply by 75:

there are 168 square feet covered with rose bushes.

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
