Question

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?

Answer 1

If x=4, replace in the given equation of perimeter to get the total distance
x=4, Perimeter = 2(5×4-2) + 2(5×4+1)
= 2(18) + 2(21)
= 36 + 42
= 78 cm

Hope it helped!

Answer 2

62 centimeters
