Find the distance between the given points (2,8) and (7,7)

Ray Of Light [21]

Answer:

$d=\sqrt{26}\approx5.0990$

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula.

The distance formula is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:

$d=\sqrt{(7-2)^2+(7-8)^2}$

Simplify:

$d=\sqrt{5^2+(-1)^2}$

Square:

$d=\sqrt{25+1}$

Add:

$d=\sqrt{26}\approx5.0990$

And that's our answer :)

Find the perimeter of the polygon on this picture. I don’t know how to do this. Plz help

ANEK [815]

The perimeter of the polygon will be given by:
Perimeter=distance around the figure
Thus the perimeter will be:
P=9.9+(9.9-5.9)+5.9+15.9+(15.9-4.6)+4.6
P=9.9+4+5.9+15.9+11.3+4.6
P=51.6
Answer: 51.6 units
