Answer find the area of a triangle with legs that are: 16 m, 12 m, and 8 m.

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=18

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

A=46.48 m²

Area of triangle is 46.48 m².

b.an increase in a causes b to decrease
