There's no question there. Something is missing. But your math book probably explains how to solve this anyway.

perimeter of triangle is sum of three sides i.e if a,b,c are three sides of triangle then perimeter is a+b+c. coming to your question answer is 13+5+x
39 centimeters.
Answer: absolutely not! Answer: No. For starters, the area uses units of area (for example, square centimeters), while the perimeter uses units of length (For example, centimeters).
The perimeter is 22.5 centimeters.
22.5
If an equilateral triangle is 3 centimeters long then the perimeter of the triangle is 9 centimeters. The perimeter is found by adding up the lengths of all the sides of an object.
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
22.5 cm
62 cm. All sides of the equilateral triang;e are the same so you simply divide the perimeter by three.
