Question

i need help finding my variable

Answer 1

The length is two times its width, and the perimeter equals 24. 

All the sides added up equal 24.

4 and 8 could be the width and the length of the rectangle.

4*2= 8 and

4+4+8+8= 24

width= 4 length= 8

I hope this helps!

Answer 2

So the length is 2 times the width, which means you double the length when adding. To find the perimeter of a rectangle, you add the sides.

l= length= 2w
w= width

l + w= 24
Substitute in the same variable as width
2w+w=24
3w=24
Divide both sides by 3
w=8 width

2w= 2(8)= 16 = length

Hope this helps!! :)
