Answer:
The area of the rectangle in terms of 'x' = 13x
Step-by-step explanation:
- Perimeter = 30 cm
- Length = x cm
Using the perimeter formula to find the width w.
Dividing both sides by 2
as P = 30 cm
cm
Using the formula of the rectangle area
substitute w = 13 and l = x in the formula
Therefore, the area of the rectangle in terms of 'x' = 13x
