The area of triangle lmn is 18 ft2 and the area of fgh is 24 ft2. if triangle lmn is equivalent to triangle fgh, what is the ratio of lm to fg?
a. 3: 4
b. 9: 16
c. square root of 3: 2
d. 4: 3

Option C

Explanation:

As we know,

Theorem of equivalent triangle states that two similar triangle's area will be proportional to square of corresponding sites.

Thus ,

On taking square root on both the sides and solving the equation further , we get -

Thus, option C is correct

b. climate change will cause an increase in biodiversity of all ecosystems.
