- 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
