Question

∆DEF~∆MNK. if DE=5, MN=6, then find the value of A(∆DEF) upon A(∆MNK)=?​

Answer 1

Answer:

A (∆ DEF ) / A (∆ MNK ) = 25/36.

Step-by-step explanation:

Given ;

DE = 5 cm.

MN = 6 cm.

∆ DEF~ ∆ MNK

Find ; value of Area ( ∆ DEF ) / Area (∆ MNK ).

Solution ;

According to 1st theorem of similar triangles :

If two triangles are similar to each other then the ratio of their area is the ration of the square of their corresponding sides .

So , Area ( ∆ DEF ) / Area (∆ MNK )

= DE ² / MN ².

= 5 ² / 6 ² = 25 / 36 cm ².
