Best ResponseYou've already chosen the best response.2I would plot the points, and connect the dots as a first step

phi

Best ResponseYou've already chosen the best response.2in a parallelogram, the opposite sides are equal. It is easy to find the length of the top and bottom sides (you count) what do you get for the length of the top side?

phi
 one year ago
Best ResponseYou've already chosen the best response.2yes, and 6 for the bottom also for the "sides" you need to use the distance formula do you know it?

phi
 one year ago
Best ResponseYou've already chosen the best response.2can you find the distance between (2,2) and (5,3) ?

phi
 one year ago
Best ResponseYou've already chosen the best response.2that is also the lenght of the other side perimeter is the sum of the 4 lengths \[ 6 + \sqrt{34}+ 6 + \sqrt{34}\]

phi

Best ResponseYou've already chosen the best response.2you can combine "like terms" to make that a bit nicer

Best ResponseYou've already chosen the best response.0Wait so you add them?

phi
 one year ago
Best ResponseYou've already chosen the best response.2yes, add the lengths. that is the definition of perimeter: total distance "around" the figure

phi

Best ResponseYou've already chosen the best response.2It is Greek: peri around, meter = measure or length

phi

Best ResponseYou've already chosen the best response.2sqrt(a) + sqrt(a) is not the same as sqrt(2*a) all you can do is say: I have one sqr(34) plus another sqr(34). How many sqr(34)'s do I have ?

phi
 one year ago
Best ResponseYou've already chosen the best response.2yes so \[ 12 + 2\sqrt{34} \] is the answer they want

Best ResponseYou've already chosen the best response.0ok so same on this one right?

phi
 one year ago
Best ResponseYou've already chosen the best response.2same idea, except opposite sides need not be equal , so it's more work First plot the points to see "what is what"

phi
 one year ago
Best ResponseYou've already chosen the best response.2yes. you can use the distance formula for all 4 sides, but for 3 of them, you can just count

anonymous

Best ResponseYou've already chosen the best response.0So Top Side = 3 Bottom Side = 9 Right Side = 5

phi
 one year ago
Best ResponseYou've already chosen the best response.2now the last side, you use the distance formula

phi
 one year ago
Best ResponseYou've already chosen the best response.2what do you get for the perimeter?

phi
 one year ago
Best ResponseYou've already chosen the best response.2that is the length of the 4th side. the perimeter is the sum of the 4 sides.

phi

Best ResponseYou've already chosen the best response.2I assume you mean 17+sqr(61)

anonymous

Best ResponseYou've already chosen the best response.0so it is \[17+\sqrt{61}\]

phi
 one year ago
Best ResponseYou've already chosen the best response.2yes, that is the perimeter of the figure, in "exact" form (we could change the sqr(61) to a decimal, but it would only be approximate)

anonymous

Best ResponseYou've already chosen the best response.0Top And Bottom are 7

phi
 one year ago
Best ResponseYou've already chosen the best response.2yes, you can do these problems

anonymous

Best ResponseYou've already chosen the best response.0\[\sqrt{89} \] for both sides right and left

Best ResponseYou've already chosen the best response.0@phi you taught me how to do this!
