The calculated area of the original rectangle is x² + 2x - 15
What is the area of the original rectangle?
From the question, we have the following parameters that can be used in our computation:
The square
Where, we have
Length = x
Width = x
The length of a rectangle is increased by 5 centimeters and the width is decreased by 3 centimeters
So, we have
Length = x + 5
Width = x - 3
So, the area is
Area = (x + 5)(x - 3)
Evaluate
Area = x² + 2x - 15
Hence, the area is x² + 2x - 15
