Question

MEDAL!!!
Matt looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one wall in the plan is 19 inches. The length of the diagonal of the floor of the room in the plan is approximately 20.62 inches.

Is the room in the shape of a square? Explain how you determined your answer. Show all your work.

Answer 1

1. the walls meet each other at right angles. (square all angles are 90 deg)
2. a2+c2=b2

right angle triangle hypotenuse theorem
with a = 19 and b = 20.62, find c
if c = a then sides are equal
so it is a square

Answer 2

how can i make this sound better/make more sense....if this is correct? @jigglypuff314 @Jaynator495

Answer 3

hey do u still need help or no

Answer 4

1. the walls meet each other at right angles. (square all angles are 90 deg)
2.
a2+c2=b2

right angle triangle hypotenuse theorem
with a = 19 and b = 20.62, find c
if c = a then sides are equal

Answer 5

Pythagoras Theorem*

Answer 6

yes i do need help:) but only if you really know what to do and can help lol..^he just copied that from the internet

Answer 7

The diagonal is the hypotenuse, so if:\[19^{2}+ 19^{2}= 20.62^{2}\]
If it is an equality, then the room is square.

Answer 8

I hope that made sense, and good luck with your studies.

Answer 9

wait...

Answer 10

Yessssss.

Answer 11

It is about 19 inches by 8 inches. so its not a square?

Answer 12

or i'm wrong lol

Answer 13

19^2+19^2=722

square root of 722 is 28.87

Answer 14

Well lets us verify. 19 squared is 361
361+361= 722
now what is 20.62 squared??? 425 not even close. The room is not square.

Answer 15

425.18

Square root of 425.18 = 20.61 .....
