Question

The perimeter of a picture frame is 24 inches. If the width of the picture frame is 5 inches, what is the length of the picture frame?

Answer 1

l=7

2l+2w=24

2l+2x5=24

2l+10=24

2l=14

l=7

Answer 2

Perimeter = Width + Width + lenght + length

24 = 5 +5 + 2length

24 = 10 + 2length

24-10 = 2lenght

14 = 2 length

14/2 = lenght

lenght = 7 inches
