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.

**Henry**, Wednesday, July 28, 2010 at 6:27pmEverything is correct, but I would

have used the Eq that I derived to

calculate A(5): A(x) = 2X^2 + 23X -12.

Michelle, you do a good job of

organizing your work; it is easy

to follow. Keep it up!
