Answer 1

To find the perimeter of a rectangle, you can use the following formula: 2W + 2L where W is the width and L is the length.

2(2x+3) + 2(4x+10)

Now we simplify the equation using the distributive property.

4x+6 + 8x+20

Now we arrange our like terms

4x+8x+6+20

Last, we combine our like terms

12x+26

So the perimeter of this rectangle is 12x+26
