Question

what is the perimeter of a triangle? (formula) like length + width + height etc...

whats the area of a triangle? (formula) like length + width + height

Answer 1

The perimiter is all sides added together.

The area is 1/2Base*Height.

Answer 2

perimeter of a triangle = add the length of the three sides

area of a triangle = 1/2 base * height

Answer 3

perimeter = side+side+side

area = 1/2base x height

If the triangle is not a right triangle then you may have to use a squared + b squared = c squared if it's an equilateral triangle (if all sides are the same length) then just cut it right down the middle to make two right triangles instead.

(a,b. and c are the sides of the triangle)

Answer 4

A = 1/2bh

P = a+b+c

:-)

Answer 5

perimeter=add the 3 sides

area of a triangle with perpendicular height= half the base multiplied by the perpendicular height

area of a triangle without perpendicular height = 1/2(a)(b) sinC(trigonometry)
