The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.
The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.
So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.
First make the 2 numbers into fractions:
13% = 13/100
260 = x/260
Cross multiply them
3380 divide by 100 is 33.80
To check do it reverse:
33.80/260 = x/100
3380 divide by 260 is 13
The answer is 33.80
