Whats the formula for the perimeter of a rectangle?

fortytherapper · Answer

Almost, that's for area though

fortytherapper · Answer

There are 4 sides to a rectangle, so it would be 2w + 2l. 2 width sides and 2 length sides

and?

...and?

Anyways, when working each answer choice, they only gave you length and width of one side, so you would need to multiply both the width and length by 2, and then combine like terms
