Ok, first you need to change the 2,000 cm into meters and then you just multiply all the sides.
14 and 11 are it dimensions
Hope this helps!
Area of a trapezoid is found with the formula, A=(a+b)/2 x h.
first, rewrite 54 as 6•9
next, rewrite 42 as 6•7
then, that gets you 6x^2 -6•7x- 6•9
lastly, factor out the common term (6)
and then you get 6(x^2-7x-9)
