Find the area of a triangle with legs that are 9mm 6mm and 12mm

Here we are given the three sides of the triangle.

So we have Heron's formula to find its area.

Heron's formula is given by :

where A, B and C are sides of triangle and S is semi perimeter which is given by,

plugging values of A, B and C to find S

S=13.5

Now plugging values of A, B , C and S in Heron's formula

A=26.14 mm²

Area of triangle is 26.14 mm².

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
