Question

The following table shows the length and width of two rectangles:

Answer 1

The correct answer is 4x-10

Answer 2

Answer:

Option A $(4x-10)$

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

where

L is the length

W is the width

Step 1

Find the perimeter of rectangle A

Substitute the values

$PA=2((2x+4)+(x-1))$

$PA=2(3x+3)$

$PA=(6x+6)\ units$

Step 2

Find the perimeter of rectangle B

Substitute the values

$PB=2((3x+1)+(2x-3))$

$PB=2(5x-2)$

$PB=(10x-4)\ units$

Step 3

Find the result of the perimeter of rectangle B minus the perimeter of rectangle A

$PB-PA=(10x-4)-(6x+6)=(4x-10)\ units$
