Question

1) Corresponding sides of two similar triangle having proportion as 3:5. Then find proportion of

area of those triangles.​

Answer 1

Answer:

ratio of there area =(3:5)whole square

Answer 2

Given :- Corresponding sides of two similar triangle having proportion as 3:5.

To Find :-

• Area ∆ABC : Area ∆DEF = ?

Solution :-

we know that,

Ratio of areas of two similar triangles = ratio of square of their corresponding sides .

so,

→ Area ∆ 1 : Area ∆ 2 = (side 1)² : (side 2)²

→ Area ∆ 1 : Area ∆ 2 = (3)² : (5)²

→ Area ∆ 1 / Area ∆ 2 = 9 : 25 (Ans.)

Similar Question for practice :-

*Corresponding sides of two similar triangles are in the ratio of 2:3. If the area of small triangle is 48 sq.cm, then t...
