lbvjy [14]

Step-by-step explanation:

You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.

Example:

Perimeter =30 Width=5

5 times 2= 10

30-10=20

20/2=10

So your length equals 10.

I hope this helps!

Find the distance between the points given.

Maru [420]

Use the distance formula

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

Input corresponding numbers

$d = \sqrt {\left( {2- 6} \right)^2 + \left( {5-8} \right)^2$

Solve

$d = \sqrt {\left( {-4} \right)^2 + \left( {-3} \right)^2$

$\sqrt{16 + 9}$

$\sqrt{25} = 5\\\\ d=5$

So, the distance between the points given is 5
