The area of the green square is 9 ft2. The area of the red square is 16 ft2.

What is the area of the yellow square?
A)
25 ft2
B)
49 ft2
C)
81 ft2
D)
128 ft2

Answer 1

You'll want to use the Pythagorean Theorem: a^2 + b^2 = c^2.

Answer 2

so ill do 9^2+16^2=c^2 and solve??? @jtvatsim

Answer 3

Well, close... What a^2 + b^2 = c^2 means is that the area of the square of the base + the area of the square of the height = the area of the square of the hypotenuse.

Answer 4

The yellow square is "the square of the hypotenuse", the green square is "the square of the height" and the red square is "the square of the base"

Answer 5

If you just add the areas of the red and green squares together you will get the area of the yellow square... it's like magic! :)

Answer 6

i Got B was that correct???

Answer 7

Did you do 16 + 9 ?

Answer 8

yah

Answer 9

OK, well, 16 + 9 = 25, and I believe choice B is 49, so...
