We know,
The ratio of the area of two similar triangles is equal to the square of the ratio of their corresponding sides
∴ Ratio of the Area of the given similar triangles = 144 : 169 ( 12² : 13²)

Let us assume the two Δ's be ΔABC and ΔDEF (refer added pic)
It is given that ΔABC similar to ΔDEF
We know that,
Ratio of Area of two similar Δ's is equal to the square of ratio of their
corresponding sides. (.i.e)
ar(ΔABC)/ar(ΔDEF) = (AB/DE)² = (AC/DF)² = (BC/EF)²
It is also give given that ratio of corresponding sides is 12/13
Then,
ar(ΔABC)/ar(ΔDEF) = (12/13)²
= 12² /13²
= 144/169
Hence Ratio of Corresponding Area = 144:169
