Question

The ratio of corresponding side if similar triangle is 5:7 then what is the ratio of their arae​

Answer 1

Answer:

25/49

Step-by-step explanation:

Since the triangles are similar, then,

A¹/A²=(S¹/S²)²

=(5/7)²

=5²/7²

=25/49

These are subscripts not superscripts above A and S(I cannot find the way to add subscripts)

Answer 2

Explanation

Let there are two tiangle;

∆

Let ∆ABC And ∆PQR

given that

∆ABC~∆PQR ; AB/ PQ=5/7

Now ratio of areas

ar (∆ABC)/ar (∆PQR)=AB^2/PQ^2=(5/7)^2=25/49=25:49
