could someone help me rectangles?

Question

The width and length of a rectangle are given by two consecutive even integers. Write an expression for the area of the rectangle. Use x for the variable.
A=

i don't know what to do

Answer 1

If your first even integer is x,

the next consecutive even integer is x+2

 

Let width w = x

Then length L=x+2

 

Area is length times width so

 

A = x(x+2)

 

A = x²+2x
