Hello again!
The perimeter is the measure of the outline of a figure. By adding all the sides, we can find it.
Area is a measure of the area occupied by an object in 2 dimensions.
So the perimeter of this triangle is just side a + side b + side c.
Regarding the area of a triangle, it is its base multiplied by its height ÷ by 2. You should know that the base of a triangle is always perpendicular to its height. So in your picture, the height corresponds to this (in red):
So the height of this triangle is 5 cm.
Now you are able to calculate your perimeter and area.
Have a nice day.
