Among all rectangles that have a perimeter of 82, find the dimensions of the one whose area is largest. Write your answers as fractions reduced to lowest terms.

12cm

the answer is d

i think this is a open ended question but i agree with other guy who said you should ask it at english section

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
