उत्तर
Let the points (−3, 5), (3, 1), (0, 3), and (−1, −4) be representing the vertices A, B, C, and D of the given quadrilateral respectively.
AB = `sqrt((-3,-3)^2 + (5-1)^2)`
= `sqrt((-6)^2+(4)^2)`
= `sqrt(36+16)`
= `sqrt(52)`
= `2sqrt13`
BC = `sqrt((3-0)^2+(1-3)^2)`
= `sqrt((3)^2+(-2)^2)`
= `sqrt(9+4)`
= `sqrt13`
CD = `sqrt((0-(-1))^2+(3-(-4))^2)`
= `sqrt((1)^2+(7)^2)`
= `sqrt(1+49)`
= `sqrt50`
= `5sqrt2`
AD = `sqrt((-3-(-1))^2+(5-(-4))^2)`
= `sqrt((-2)^2+ (9)^2)`
= `sqrt(4+81)`
= `sqrt85`
AC = `sqrt ([0 - (-3)^2] + (3 - 5)^2)`
= `sqrt ((3)^2 + (-2)^2)`
= `sqrt (9 + 4)`
= `sqrt13`
BD = `sqrt ((-1 - 3)^2 + (-4 - 1)^1)`
= `sqrt ((-4)^2 + (5)^2)`
= `sqrt (16 + 25)`
= `sqrt41`
It can be observed that all sides of this quadrilateral are of different lengths. Therefore, it can be said that it is only a general quadrilateral, and not specific such as square, rectangle, etc.

Find distance between point A(–1, 1) and point B(5, –7):
Solution: Suppose A(x1, y1) and B(x2, y2)
x1 = –1, y1 = 1 and x2 = 5, y2 = – 7
Using distance formula,
d(A, B) = `sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2`
∴ d(A, B) = `sqrt(square +[(-7) + square]^2`
∴ d(A, B) = `sqrt(square)`
∴ d(A, B) = `square`

In a GPS, The lines that run east-west are known as lines of latitude, and the lines running north-south are known as lines of longitude. The latitude and the longitude of a place are its coordinates and the distance formula is used to find the distance between two places. The distance between two parallel lines is approximately 150 km. A family from Uttar Pradesh planned a round trip from Lucknow (L) to Puri (P) via Bhuj (B) and Nashik (N) as shown in the given figure below.
