Question

If a rectangle has side lengths x+4 and 2x what is the perimeter and area of the rectangle?

Answer 1

Perimeter: 6x+8

Area: 2x²+8x

Explanation:

Perimeter- the sum of all sides

So, you do x+4+x+4+2x+2x

Simplify that to- 2x+2x+2x+8

And also simplify that to- 6x+8

Area- length*width

So, it's (x+4)*2x

which is 2x²+8x
