If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
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.
The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.
It depends on what you wish to measure: the lengths of sides, the angles, the area, the perimeter.
to find the area of a triangle you divide the base of the triangle by two and multiply your answer by the height .so your formula would be 1/2b times h to find the perimeter of a triangle u simply just add the sides.
