The hedge boundary needs to be planted around a rectangular lawn 18 m long and 12 m wide. if 3 shrubs can be planted to grow a metre hedge, how many shrubs will be needed in all?

Step-by-step explanation:

let P represent the perimeter of the rectangle

P = 2×(12 + 18) = 2×(30) = 60 m

then

the number of shrubs = 3×(60) = 180

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
