approximate area of this region If the square has a

perimeter of thirty two and here the potential answers So

before we spoil the ending hit pause and try this

one yourself Okay this is a multi party way Have

to remember the formula for the perimeter of a square

And then we have to be able to read a

graph with this scurvy line thing So first off a

square got its name because it means that all four

sides are equal were socialists two sides good four sides

better So if the total perimeter is thirty two and

there are four sides what's thirty two divided by four

in california that's right Each side has a length of

eight And who Curveball Note that one of the answers

here is eight Beware that h is on ly the

distance of one side of the squares and knowing that

fact is a big part of the question Like if

we didn't know how to make that initial fancy drawing

in the beginning we'd be in real trouble Oh now

we have to apply that eight unit distance to the

graph and if we start here and move straight upwards

until we hit the curve way hit it here and

come straight left to hit the y axis here So

where is here Well note that this line is halfway

between forty eight zero so it's gotta be twenty four

in our line hits halfway between the twenty four forty

eight so that line hits thirty six answers See don't

worry we won't forget to invite you to the bris 00:01:47.714 --> [endTime] Two sides Good four side's better
