The perimeter of a triangle is 80 centimetres and its sides are in the ratio. 5: 7: 8 . Can you compute the actual lengths of sides?

In writing the equation to construct a rectangle of specified perimeter and area, the perimeter,was wrongly written as 24 instead of 42.The length of a side was then computed as 10 metres.What is the area in the problem?What are the lengths of the sides of the rectangle in the correct problem?
