Answer 2

What do u think ?

Answer 3

tbh i'm not really sure.

Answer 4

Since it's a square width = length
Area = width *length right?
for a square area = width * width
\[Area = width ^{2}\]
\[width = \sqrt{area} = \sqrt{169} =13ft\]

Answer 5

width = length so no difference

Answer 6

any doubts?

Answer 7

i still don't understand it.

Answer 8

which part

Answer 9

area = width * length right?

Answer 10

in a square width = length
So we can write area = width * width OR area = length * length right?

Answer 11

area = a^2 (a being the side length) so in order to find the side length you would do the square root of 169. The side length would be 13.

Answer 12

Imagine that we have a square with an unkonw side length "X'
Then area = X*X
\[Area = X ^{2}\]
\[X = \sqrt{Area} = \sqrt{169} = 13\]
