The bottom equation states that:
Triangle Area = side^2 * (sqr root 3) / 4 or
Triangle Area = side^2 * .4330127..
So, we'll say the side originally equaled 1 and the new length is 7% longer ot it equals 1 + .07 or 1.07
Looking at the formula:
Triangle Area = 1.07^2 * .4330127...
the .4330127 doesn't change but the side increases to 1.07
and the change in area is 1.07^2 or 1.1449 times larger.
So, the area is 14.49% larger.
