Question

how you do this:

The perimeter of an isosceles triangle is 36cm, and the area is 60cm. The length of the base is 3cm less than the length of a leg. Find the length of each side.
Let X = length of one of the legs.

Perimeter = 2X + (X - 3) = 36

3X = 39

X = 13

Check by inserting that value into the formula for the area.

I hope this helps. Thanks for asking.
x= 13
