If the sides of two similar triangles are in the ratio of 3:5, find the ratio of their areas.

Kazeer [188]

Ratio of areas of similar triangles is 9 : 25.

Solution:

Given data:

Ratio of sides of two similar triangles = 3 : 5

To find the ratio of areas of the triangles:

We know that,

<em>In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.</em>

$$\text{Ratio of areas} = \frac{\text{Area of triangle 1}}{\text{Area of triangle 2} }$

$$=\left(\frac{3}{5}\right) ^2$

$$=\frac{9}{25}$

Ratio of areas of similar triangles is 9 : 25.

<h3>Answer :</h3>

$\: \: \:$

$= \rm \large \frac{3 \frac{1}{2} - 9 \frac{3}{4} }{ - 2.5}$

$\: \:$

$= \rm \large \frac{ \frac{7}{2} - 9 \frac{3}{4} }{ - 2.5}$

$\: \:$

$= \rm \large \: \frac{ \frac{7}{2} - \frac{39}{4} }{ - 2.5}$

$\: \:$

$= \rm \large \: \frac{ \frac{25}{4} }{ - 2.5}$
