Swimming space. The length of a rectangular swimming pool is 2x-1meters, and the width is x+12 meters. Write a polynomial A (x) that represents the area. Find A (5)

Answer:

Area=(2x-1) (x+12)sq m

A=2x(x+12)-1(x+12)

=2x^2+24x-x-12

=2x^2+23x-12 sq m

X=5

A=(2(5)-1) (5+12)

=9*17

=153 sq m

I need to know if I have this correct and if not what I done wrong.
