Justin calculates the perimeter of a rectangle with a length of 2x-3 and width
of X+4. He tells his teacher the answer is 3x-1. Is he correct or incorrect and why?



Answer :

Answer:

No

Step-by-step explanation:

No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.

Answer:

No, his answer should have been 6x+2

Step-by-step explanation:

The equation for perimeter is 2L+ 2W=P

so 2 (2x-3) + 2 (x+4) = 6x+2
