Mathematical processes are the steps used to determine the result of operations
- The perimeter of the rectangle is

- The area of the rectangle is

The dimension of the rectangle is given as:


<u>(1) The perimeter of the triangle</u>
This is the sum of the side lengths of the rectangle.
So, we have:

This gives

Collect like terms

Open brackets

Hence, the perimeter of the rectangle is 
<u>(2) The area of the triangle</u>
This is the product of the dimensions of the rectangle.
So, we have:

This gives

Open brackets

Collect like terms


Hence, the area of the rectangle is
