Herbert is decorating the bulletin board in the school's lobby. The bulletin board is a 7 ft by 11 ft rectangle. He decides to add a black border around the entire bulletin board. What is the length of border that he needs?

36 feet

Step-by-step explanation:

The length of border that Herbert needs simply means that we've to calculate the perimeter.

The sides of the rectangle are 7 ft by 11 ft. The perimeter of a rectangle will be:

= 2(Length + Breadth)

= 2( 7ft + 11ft)

= 2 × 18

= 36 feet

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step- i d k and i d c : )

you: : 0
