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:
Let the cost of the computer be $
and the cost of the software be $
The total cost the business owner incurred was $
This means that,
We were given another information concerning the relationship between cost of the computer and that of the software.
That is, the computer costs 4 times the software.
Mathematically, we express this relation as,
Now, we substitute equation 2 into equation 1 to obtain,
We simplify to get,
Divide both sides by 5.
Simplify to obtain,
Hence the cost of the software is $800
