I have a question.
can you help me.

The question is, Find the side length of a square that has a permeter of 32cm?

im not understanding the part where it says find the side length.
because to fing the area you need to do width x length.
so how do i get the perimeter?
Answered by Writeacher
The perimeter is the measurement around the outside. So adding the 4 sides together equals 32 cm. How long do you think each side is?
Answered by Taylor

i have another question about squares?
the question is,
a square has an area of 81 square feet. what is the length of each side?

i don't really know because it doesn't show the width so i can't do w.l
?? what do i do?
Answered by Writeacher
area = length x width

Since a square has equal length and width, obviously all 4 sides are equal.

So ... what x what = 81 ??
Answered by Taylor
i don't know.

my answer would be

81 / 4 = 20.25
??

it doesn't make since though??
Answered by Writeacher
No that doesn't make sense.

Area = length x width
No division involved; no addition involved; no subtraction involved. Only multiplication.

___ x ___ = 81
Think back on your multiplication tables.

Answered by Writeacher

So each side is 9 ft.
