Answer:

Area = [tex]4x^2+100x+600[/tex]


Step-by-step explanation:

If both length and width are increase by 2x meters each, then:

New length = 30 + 2x

New Width = 20 + 2x


We know area of rectangle = length * width

Thus the new rectangle will have an area of :

Area = length * width = [tex](30+2x)(20+2x)=600+60x+40x+4x^2=4x^2+100x+600[/tex]


Note: Standard form of a polynomial is writing the terms in order (highest order comes first and so on)
