Answer :

The area of an equilateral triangle of side a =


A=


Here A1 =


Now, if the side is tripled, the side it becomes 3a


the new area is


A=


A=


A =


A = 27 A1


The increase in percentage of the area of the equilateral triangle


=


=


= 26 × 100


= 2600


Hence the % increase in area of equilateral triangle is 2600 %
