If you have 140 meters of fencing and want to enclose a rectangular area up against a long, straight wall, what is the largest area you can enclose?

the area of rectangular is  A= length x width
 
  140 feet of fancing = (the above line)

        !!                                     
        !                                                   !
     x !   thelargest enclosed area      ! x
        !                                                   !
        ! !
                          140 -(x+x)
so the area is  A = (140-2x) (x)= 140x-2x²

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
