Hello!

❖ There are a total of 18 marbles.
In order to get 18, we have the ratio 2:1. 2 represents the blue marbles and 1 represents the red marbles. We now have 12 blue marbles in a box. 2 x 6 = 12 so we are multiplying by 6. What we do to one number, we do to the other so 1 x 6 = 6 . Add 12 + 6 = 18

Yo sup??
Lenght of two side will be equal to 20 in as its an isoceles triangle.
The third side will be
x^2=b^2+h^2 (by pythagoreas theorem)
=9^2+9^2
x=9√2 in
Therefore the perimeter is = 9+9+9√2
=9√2(√2+1) in
Hope this helps.
