The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is 2l + 2w = 16, where l represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle?

7 in.
8 in.
9 in.
10 in.

Respuesta :

the answer is 7 inches because it satisfies with the situation.
eg: 2*7 + 2*w=16
     ⇒14 + 2w=16
     ⇒w=16-14/2=1inch
If l=8, then
    2*8 + 2w= 16
⇒w=0 
So it wont form a rectangle
If l=9
2*9 + 2w=16
⇒w=16-18/2
⇒w=-1
And width or length can't be negative.....
hope I helped!
