8 = 4 w divided by 3

Answer:

The length of the window is 35 inches.  

Step-by-step explanation:

Perimeter of an object can be found using the general formula:  P = 2W + 2L, where P = perimeter, W = width and L= length.  Since both the width and perimeter of the window are given, we can plug these values into the formula to solve for the missing variable 'L':  112 = 2(21) + 2L, or 112 = 42 + 2L.  We can then use inverse (opposite) operations to isolate the variable and solve.  Whatever we do to one side of the equation, we do to the other.  We will start by subtracting 42 from each side:  112 - 42 = 42 - 42 + 2L or 70 = 2L.  Next, we divide both sides by 2 to solve for L:  70/2 = 2L/2 or L = 35.  So, the final length of the window is 35 inches.  

If one piece is 5/6 feet, second is 5//3 feet and third is 3/2 feet long then the range of length is from 0.81 to 1.67 feet.

What is range?

Range is basically a limit under which the value of something lies. It can be a value of function or any other variables. If we have given range of a variable then we don't get the value of that variable beyond that range.

How to find range?

We have been given that Ikki has 3 pieces of yarn and  first piece is 5/6 feet long,second is 5/3 feet long and the third one is 3/2 feet long.

To find out the range we have to first make the above fractions in decimal form by completing the division.

First part is 5/6 =0.81 feet.

Second part is 5/3=1.67 feet

Third part is 3/2 =1.5 feet

Largest part is second and smallest part is first. So the range of length is from 0.81 to 1.67.

Hence the range of length of yarn is from 0.81 to 1.67.
