They give you the equation, $$\frac{1}{2}~b\times~h~=~A$$you are also given your base and height measurements. Plug them into the equation and solve for the polynomial equation.

@thomaster can you help with this one?

thomaster · Answer

$$\frac{ 1 }{2 }(7x-3)\times(2x+2)~=~Area$$

anonymous · Answer

Thanks! i have one more question

anonymous · Answer

Find the area of the parallelogram, A = bh. Leave the answer in simplest polynomial form.

anonymous · Answer

wait @thomaster is   12(7x−3)×(2x+2) the answer to the first one or do i have to simplify it?

thomaster · Answer

you can simplify it yes first multiply 1/2 with the first parenthesis set
$$\frac{ 1 }{ 2 }(7x-3)~=~3.5x-1.5$$So $(3.5x-1.5)(2x+2)$

anonymous · Answer

alright and what about the second one

anonymous · Answer

@thomaster

thomaster · Answer

Same thing. paralellogram = base * height
You know both 

$(2n+3)(n+8)$

anonymous · Answer

is that the simplest form?

thomaster · Answer

they ask the polynomial form so you have to foil it

thomaster · Answer

Same for the first one
