Pattern for circles is 4 x (n-1) + 1 where n is your figure number

Pattern for triangle is nxn x 4 where n is your figure number

No it is not. The formula is deduced from the pattern. Different pattern have different formula

Ha ha.. I didn’t know the method.
Normally we Try to solve using formula.
Like triangle. .. the formula is (nxn) x4
Example
Figure 1, (1x1) x4=4
Figure 2, (2x2) x4=16
Figure 3, (3x3) x4= 36
Figure 4, (4x4) x4 = 64
.
.
.
If question ask for figure10
Then (10x10) x 4 = 400.
