Answer 1

Answer:

289

Step-by-step explanation:

in each triangle, if we add all the digit of corner no., you will get a no. whose square is written inside the triangle.

for e.g in triangle 1. (3+5)+(3+1)+(2+1)=15, now square of 15=225

in triangle 2. (1+1)+(5+1)+(3+1)=12, now square of 12=144

so, in triangle 3. (1+7)+(1+3)+(2+3)=17, now square of 17=289.
