How does tripling the side lengths of a right triangle affects its area?

Let be the lengths of the original legs. The original area is thus

Now, we triple the legs, so we have

The new area is

which is 9 times the original area.

So, if you triple both legs, the area will be nine times as much as the original one.

the answer is d

step-by-step explanation:

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.
