Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. The perimeter of the rectangle is 2(5x – 2) + 2(3x + 1). If x = 4 centimeters, what is the total distance Zohar needs to cut with the scissors?

Respuesta :

Replacing x by 4 in the above equation, you get:

2(20-2)+2(12+1)
2(18)+2(13)
36+26
=62 cm

As simple as that.
