Question

Malia is planting a garden in her yard.The dimensions are represented by x+4 feet and x+8 feet. She needs fencing to go around the perimeter of the garden to keep animals out. Which expression represents the amount of fencing she will need in feet. 4x+24 2x+12 (x+8)+(x+4) x^2+12

Answer 1

I think you would have to do 2(x+4)+2(x+8) because it it talking about perimeter and if you imagine a square or rectangle, there are four sides, so just adding x+4 and x+8 wont be the whole perimeter. So, if you solve the expression 2(x+4)+2(x+8) it will give you 4x+24 XD
