The answer is 72 square inches, since there are 24 triangles, and you do 36*48/24, which equals to 72.
(r+b-g)(b-g)
I this question , we have the values of r,b and g given , which are r=9,b=5,g=6
And we have to find the value of the given expression . And for that we need to substitute the values of r,b and 9 in the expression. That is ,
(9+5-6)(5-6) = 8(-1) = -8
So the value of the given expression is -8.
Depending on how big the center is, I would say 15.
I hope this helped!
