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
