The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?

Question

can anyone help me with this?

Answer 1

area = length*width ...

length = area/width

 

l = (x²+8x+15)/(x+3)

 

l = [(x+5)(x+3)]/(x+3) = x+5

 

The length is x+5
