Question

∆ DSA ~ ∆ XYZ .if DS = 15 cm and XY = 12 cm then ar (XYZ ) /
ar (DSA) =​

Answer 1

Step-by-step explanation:

Given:-

∆ DSA ~ ∆ XYZ .

DS = 15 cm

and XY = 12 cm

To find:-

Find the value of ar (XYZ ) / ar (DSA) ?

Solution:-

Given that

∆ DSA ~ ∆ XYZ .

DS = 15 cm

XY = 12 cm

Since , ∆ DSA ~ ∆ XYZ=∆ XYZ~∆ DSA then the ratio of area of the two triangles is equal to the ratio squares of the corresponding sides.

=> ar (XYZ ) / ar (DSA)

= (XY/DS)^2 = (YZ/SA)^2=(ZX/AD)^2

=> (XY/DS)^2

=> (12/15)^2

=> 12^2 / 15^2

=> (12×12)/(15×15)

=> 144/225

ar (XYZ ) / ar (DSA) = 144/225

Answer:-

The ratio of the areas of the two triangles

ar (XYZ ) / ar (DSA) is 144/225

Used formulae:-

The ratio of the areas of two similar triangles is equal to the ratio of the squares of the corresponding sides.
