1st : each side of the triangle (or one side of each square ) is gonna be
side 1 : a + 4
side 2 : a + 2
side 3: a
2nd : add all sides and square it so it will be..
(a+4)² + (a)² + (a+2)² = 155
3rd: bring 'a'
you could just put the whole thing in the calc then 'shift+solve+equale sign'
( put it as x in the calc not 'a' )
a = 5
4th: substitute 5 with 'a' in the largest area which is (a+4)²
(5+4)²
therefor, the answer is 81
