# The Areas of Two Similar Triangles Are in Respectively 9 Cm2 and 16 Cm2. the Ratio of Their Corresponding Sides is (A) 3 : 4 (B) 4 : 3 (C) 2 : 3 (D) 4 : 5 - Mathematics

MCQ

The areas of two similar triangles are in respectively 9 cm2 and 16 cm2. The ratio of their corresponding sides is

•  3 : 4

• 4 : 3

•  2 : 3

• 4 : 5

#### Solution

Given: Areas of two similar triangles are 9cm2 and 16cm2.

To find: Ratio of their corresponding sides.

We know that the ratio of areas of two similar triangles is equal to the ratio of squares of their corresponding sides.

\text{ar(tringle 1)}/\text{ar(tringle 2)}=(\text{side1}/\text{side2})^2

9/12=(\text{side1}/\text{side2})^2

Taking square root on both sides, we get

$\frac{\text{side1}}{\text{side2}} = \frac{3}{4}$

So, the ratio of their corresponding sides is 3 : 4.

Hence the correct answer is a
