Question

A rectangle poster has a length of 24 inches,what is the perimeter of the poster?

Answer 1

Answer: 72 inches

Step-by-step explanation:

To find the perimeter of a rectangle, simply follow this equation:

$L+L+W+W$

Or alternatively,

$2L+2W.$

• We know that the Length (L) is equal to 24 inches and the width (W) is 12 inches.

So just add it into the equation and solve!

- Option 1

$24+24+12+12 = p\\48+24=p\\72=p$

- Option 2

$2(24)+2(12)=p\\48+24=p\\72=p$

Either way you do it, the answer is 72 inches.
