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?

**Writeacher**, Monday, January 7, 2008 at 8:07pmThe perimeter is the measurement around the outside. So adding the 4 sides together equals 32 cm. How long do you think each side is?

**Taylor**, Monday, January 7, 2008 at 8:18pmi 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?

**Writeacher**, Monday, January 7, 2008 at 8:20pmarea = length x width

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

So ... what x what = 81 ??

**Taylor**, Monday, January 7, 2008 at 8:25pmi don't know.

my answer would be

81 / 4 = 20.25

??

it doesn't make since though??

**Writeacher**, Monday, January 7, 2008 at 8:29pmNo 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.
