the base of an isosceles triangle i 5 and its perimeter is 1. the base of a similar isosceles triangle is 10. what is the perimeter of the larger triangle?
I think you mistyped the perimeter. Set the problem up
base i/perimeter i = other base/perimeter
the multiply across the equal sign top to bottom then divide by the other number. using what you have given above, it would be
5/1 = 10/x
10 times 1 divided by 5 so the answer would be 2. They are all set up the same, no matter your numbers.
