Question

Help me? Am I right?

If the dimensions of a rectangle become one-third of the original dimensions, then area of the new rectangle will be _______of the area of the original rectangle. Enter your answer in numerical form, using the / for the fraction bar if needed.


_____ is 1/3?

Answer 1

lets take a real example.

Let dimensions be multiples of 3 like 6,9

Then area would be 6x9 = 54.

Now if dimensions are 1/3rd i.e. 2, 3,

Then area will be 2x3 = 6.

and 6 is 1/9 of 54.

So actually speaking, if u 1/3rd the length of 2 dimensions, the area will fall by square of 1/3 which is 1/9, since ur multiply 1/3 of x . 1/3 of y which is 1/9 xy.

Answer 2

I don't get it. If it can't be 1/3, then what can it be?

Answer 3

Oh, so the answer is 1/9!!! I get it now, Since the original triangle was 1/3 the new triangle is going to be 1/9!!

Answer 4

rectangle. :P

bcoz ur multiplying 1/3rd of two sides which is (1/3)^2 = 1/9 simple as that :)
