If anna had a jewelry box with width of w and length of 4w - 3, calculate the perimeter of the jewelry box when the width = 8 cm.

Hey there!!

Perimeter of a rectangle = 2 ( length + breadth )

Width is given by ' w '

Length is given by  ' 4w - 3 '

Now, let's plug in the values ...

2 ( 4w - 3 + w ) = perimeter

2 ( 5w - 3 ) = perimeter

10w - 6 = perimeter

And then, w is given by 8 cm

10 ( 8 ) - 6

80 - 6

74 cm

Hence, the perimeter is 74 cm

Hope my answer helps!!
