Question

a square plot of land has an area of 100m what is the perimeter of the land

Answer 1

how many equal sides does a square have?

Answer 2

4

Answer 3

how many \(\bf \text{equal sides}\) does a square have?

Answer 4

and yes, it has 4 total

Answer 5

so then 400????

Answer 6

?

Answer 7

well.... it's a SQUARE.... so... how many sides that are EQUAL to each other, does a SQUARE have? 2 sides? maybe?

Answer 8

You are given the *area* of a square... that means you can find the length of one side.
if you know the length of one side, you can find the perimeter.

Answer 9

Do you know the formula for the area of a square ?

Answer 10

Yeah a= lw

Answer 11

true, but l and w are the same for a square.

Answer 12

how about Area= L*L (L is the length of any side)
100 = L^2
can you find L ?

Answer 13

Do you know about square roots ?

Answer 14

it doesnt give me a little picture it just is a word problem.

Answer 15

We don't need a picture.

L^2 = 100
can you find L using square root of both sides ?

Answer 16

\(\bf Area = x^2\qquad Area = 100m\\ \quad \\
100=x^2\implies x=?\)

Answer 17

\[area = 100m ^{2}\] Thus the side(α) equals:\[\alpha=\sqrt{100}m=10m\]
and the perimeter equals:
\[4\alpha=4*10=40m\]
