Question

Help Please!!!
1.A kid run around a field which shapes is rectangle with the length 16 Meter. if he run around the field two times,so he already managed the distance of 108 Meter.

a. create a mathematic model from that,and finish it.
b. what is broad field such?
i really appreciate anyone who help me right now.
thank you :)

Answer 1

the field is 16 meters long and 2 laps around it is 108 meters. That means that the perimeter is 54 meters. 2 sides are 16 meters which means that the other 2 sides have to be 11 meters. As for the model of the field, it would be a rectangle with the dimensions of 16x11. I could be wrong but that is my understanding of your question

Answer 2

i see.. but what i asked is in a. and b. .. but i aprreciate your answer,though. thank you very much :D

Answer 3

your welcome hope i helped you in some way

Answer 4

yeah,you helped me find how to search the broad of the field :D again,thank you very much :)

Answer 5

good luck with the rest of it

Answer 6

haha,yeah. i'll try then :)

Answer 7

mathematic model ? you mean frame an equation ?

Answer 8

@jiehanthelearner ?

Answer 9

yeah,some sort. i mean,a mathematical problem from that topic

Answer 10

ok

its a rectangle so perimeter will be 2(l+b) where l is length and b is breadth .
Now the kid made 2 runs that will be

2 X 2(l+b)=4(l+b)

It is said the kid managed 108 meter when doing this .Hence we can equate this to 2 times perimeter

4(l+b)=108

Also given length=16 m

substituting

4(16+b)=108

^^This I suppose is the mathematical model of the question

Now to find breadth just open the brackets and solve for b


I hope that helps :)
