A+b+c=6, a=2c, b=a+c using a and b in the first equation gives you:
2c+a+c+c=6 now use a=2c again
2c+2c+c+c=6
6c=6
c=1, since a=2c
a=2, since b=a+c
b=3
So the number is 231.
The answer is A which is 18 square inches. This is because the formula for finding the area of a triangle is 1/2 multiplied by the length of the base multiplied by the height. And so when you calculate this, you will get 18 square inches :)
