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 if 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

62 cm

Explanation:

P = 2(5x - 2) + 2(3x + 1) Insert the value of x

P = 2(5×4 - 2) + 2(3×4 + 1)

P = 2(20 - 2) + 2(12 + 1)

P = 2×18 + 2×13

P = 36 +26

P = 62 cm

Zohar must cut 62 cm with the scissors.
