How do you find the length if you already know the perimeter? this is what i mean:

morgan is ordering carpet for her bedroom. she measures the room and finds a width of 22 feet and a perimeter of 66 feet.

i know for sure that the first thing i need to do is find the length, but how do i do that with only knowing the width and perimeter?

You can find length by knowing the formula for perimeter: 2l+2w= p; where l= length, w= width, and p= perimeter. Substitute the things you know and solve.

In this case, the length would be 11 feet.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
