**L**, Thursday, December 2, 2010 at 12:28amMake an equation to help you solve!

We know that:

Side1=16cm

Side2=Side3

Let's name Side1 x, and Side2 and Side3 (Because they are the same) y.

Perimeter=Side1+Side2+Side3

Perimeter=x+y+y

Perimeter=x+2y

Sub in your value for x:

P=16+2y

Now, we also know that:

2P=(Side1+24cm)+(Side2+24cm)+(Side3+24cm)

2P=x+2y+72

2P=2y+72+16

2P=2y+88

Let's isolate for P:

2P=2y+88

(2P)/2=(2y+88)/2

P=y+44

Now we can equate the two equations to find y, because P=P!

Good luck (:
