Question

How do you find the perimeter in simplest form?

Answer 1

add all sides..

Answer 2

yes, add all the sides of the given figure.

Answer 3

it depends on the figure. there is no fixed formula for perimeter but it's the sum of all the sides of the polygon like they said

Answer 4

Here are the sides it has: x-6 and x+8

Answer 5

is it a rectangle?

Answer 6

yes

Answer 7

then the perimeter is P = 2(L + w)

so perimeter here is just

P = 2( x - 6 + x + 8)

do you know how to simplify that?

Answer 8

No

Answer 9

do you know what x + x is?

Answer 10

hint: x + x is just like 1 + 1

Answer 11

1 + 1 is 2*1
So x + x = 2*x which can be written as 2x
Similarly x + x + x + x + x = 5x and so on.

Answer 12

perimeter is just the sum of all sides.
In case of rectangle, the opposite sides are equal.
So, perimeter = (x-6) + (x+8) + (x-6) + (x+8)
= (1x+1x+1x+1x+4)
= 4x + 4 Ans.

Answer 13

Alright, I think I got it now. Thank you all for your help!
