The rectangle has width x feet, and its length is five feet longer than its width what is the expression

Answers

Answer 1
Answer: x^2 +5x Should be your answer because:
Rectangle area=width * length 
Width= x 
Length=x+5 
Rectangle area=x*(x+5)=x^2 + 5x, 

I hope this helps!
Answer 2
Answer: So the given is that the width is x feet
and that the length is 5 feet longer than its width

Width = x
Length = 5 + x

More:
If you want to find the perimeter:
2 × width + 2 × length
2 × (x) + 2 × (5 + x)            -              it is a rectangle
2x + 10 + 2x
4x + 10 ft

If area:
width × length
x × (5 + x)
5x + x² ft²
