Please help, my teacher is going mad!

It is a rectangle.

LENGTH = 5 X+2   IF X = 5        L = 5×5+2 =25+2=27

L=27

BREADTH = X+8 IF X=5     B =5+8= 13

B= 13

Area of the rectangle = L× B

                                       =27×13

                                    = 351

Perimeter of the rectangle=2(l+b)

                                        =2(27+13)

                                     =2×40

                                    =80

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
