Answer 1

do u know how to find the length of a straight line when the coordinates of 2 points r given ?

Answer 2

ADD THEM ?

Answer 3

no...
let;s say
the coordinates of A is ( x1 , y1)
and the
coordinates of B is ( x2 , y2)
then the length of line AB is
\[AB = \sqrt { ( y_{2} - y_{1} )^{2} + (x_{2} - x_{2})^{2}}\]

Answer 4

now the perimeter of the figure u got is
AB + BC +CD + DE +EA
u have to find the length of
AB
BC
CD
EA
seperately

Answer 5

i will help with u finding the length of side AB ... the rest is up to u ok :) ?

Answer 6

is it 7 ?

Answer 7

the coordinates of
point A = (2, 0)
point B = ( -4 , 5)

now according to the above equation
x1 = 2
x2 = -4

y1 = 0
y2 = 5

then
\[AB = \sqrt{ ( 5 - 0)^{2} + (-4 - 2 )^{2} }\]

Answer 8

\[AB = \sqrt{ 25 + 36 } = \sqrt{ 61}\]

Answer 9

now... follow the same procedure for the remaining lines
1. chose the line u want
2 . take the pair of coordinates at the 2 ends
3. substitute them in the given equation
can u do that :) ?
