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?
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?
thank you,would it be 8cm?
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?
area = length x width
Since a square has equal length and width, obviously all 4 sides are equal.
So ... what x what = 81 ??
i don't know.
my answer would be
81 / 4 = 20.25
it doesn't make since though??
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.
9 x 9 = 81
yes!!! 9 x 9
So each side is 9 ft.
