Find the distance between the points (2,-9) and (-1,4)

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2,-9) and (-1,4)

The distance between them is

We have the final answer as

Hope this helps you

≈ 13.3

Step-by-step explanation:

Calculate the distance using the distance formula

d =

with (x₁, y₁ ) = (2, - 9) and (x₂, y₂ ) = (- 1, 4)

d =

   =

   =

   = ≈ 13.3 ( to 1 dec. place )

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
