The length of one side of a squar city is 465 meters . What is the perimeter of the block

1860meters

Step-by-step explanation:=Step one:

given data

The length of one side of a square city is 465 meters

We know that perimeter= 4L

P=4*L

Step two:

substitute

P=4*465

P=1860meter

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
