An angle cannot have an area.
It is possible, however, that the question is about a right angled triangle.
Suppose the lengths of the two legs are x cm and y cm
by Pythagoras, x2 + y2 = 52 = 25
and perimeter = 12 => x + y + 5 = 12 => x + y = 7
So (x + y)2 = 49
ie x2 + 2xy + y2 = 49
But x2 + y2 = 25
so 2xy = 49 - 25 = 24
So area of triangle = 0.5*xy = 24/4 = 6 sq cm

What is the perimeter of a triangle that has sides 4cm long?
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
A right triangle has the hypotenuse 12cm and an angle 30 degrees what is the opposite angle?
A right triangle with a hypotenuse of 12cm and an angle 30 degrees has an opposite angle of: 60 degrees.
How do you draw a triangle with a perimeter of 12cm and area of 6cm2?
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
Could an isosceles triangle have a perimeter of 12cm and area of 12cm2?
No. The maximum are is attained when it is equilateral and that is less than 7 cm2
You are given that triangle mnp triangle xyz line mp equals 8cm line xz equals 12cm the perimeter of triangle xyz equals 80cm what would be the perimeter of triangle mnp?
It is necessary to mention that the two triangles are similar.Let the perimeter of the triangle MNP be x cm.Since the triangles XYZ and MNP are similar triangles,8/12 = x/80 (multiply both sides by 80)640/12 = x53.3333... = x53 3/9 = x53 1/3 = xThus, the perimeter of the triangle MNP is 53 1/3 cm.
