Sorry, can u explain on the method used?
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.
To find a common formula for the results
