Question 936895
 area  = 72 sq m
  formula:
 area  = {{{ (1/2)*base*height)
 base =height
 let x be the length of base and height
 area  = {{{(1/2)* x*x}}}
 {{{ 72 = (1/2)*x*x}}}
    {{{72*2 =x*x}}}
      {{{ 144=x^2}}}
    {{{ sqrt(144)=x}}}
  {{{ 12=x}}}
 base=height  = x=  12 m
length of other two sides  = 12 m
