Swimming space. The length of a rectangular swimming pool is 2x 1 meters, and the width is x + 2 meters. Write a polynomial a(x) that represents the area. Find A (5).

Area = length * width
length = (2x1)m
width = (x+2)m
Area = (2x1)(x+2) m^2
Multiply the two factors (use FOIL).

Area=Length*Width
Length = (2x1)m
Width = (x+2)m
So, Area = (2x1)(x+2)m^2
Substitute the "x" with 5.
So, Area= (2(5)1)(5+2)m^2
Solve for Area now
Area= (9)(7)m^2
Area= 63m^2
