Step-by-step explanation:
Given
--- rectangles
Required
The perimeter of square in the middle
The area of a rectangle is:
So, we have:
The perimeter is:
So, we have:
Divide by 2
Make L the subject
Substitute in
Open bracket
Rewrite as:
Expand
Factorize
Factor out W - 3
Solve for 7
We have:
This means that:
The length (l) of the square is:
---- the difference between the dimension of the rectangle
The perimeter is:
6 go from one side to the other until you come up with the middle number if you get two numbers find the average
The volume of the shed will only be 1/8 of the original size.
If each of the measurements is cut in half, that means it is being reduced by 1/2.
To find the volume, we have to multiply the length by width by height.
These means that we have to multiply:
1/2 by 1/2 by 1/2 = 1/8
