today we're gonna solve the Arian

perimeter of a rectangle a rectangle

remember has two sets of congruent sides

or equal sides so this is 12 then the

top is also 12 if this side is 7 then

this side is also 7 so in order to solve

for the area of a rectangle we need to

think of the formula and the formula is

length times width find the inside the

areas on the inside so the length is

going to be 12 times the width which is

over here that's 7 so when I do 12 times

7

you get 84 meet the label it's in

centimeters so the answer is 84 square

centimeters to find the perimeter member

the perimeter is just adding all the

sides so if you see here a rectangle has

one two three four sides so we're gonna

add four numbers we're gonna add 12 plus

12 and then 7 plus 7 when we add all

those sides you get 38 centimeters so

our perimeter is 38 centimeters
