In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle by

uysha [10]

Answer:

C) $6.495\: ft^2$

Step-by-step explanation:

a = 7 ft, b = 3 ft, c = 5 ft (Given)

Therefore, a + b + c = 7 + 3 + 5 = 15 ft

Let's calculate semi Perimeter of the triangle which is given by s

$s =\frac{a+b+c}{2}=\frac{15}{2} = 7.5 \: ft$

Now, by Heron's formula, area of triangle ABC is given as:

$A(\triangle ABC) =\sqrt{s(s-a) (s-b)(s-c)}$

$\therefore A(\triangle ABC) =\sqrt{7.5(7.5-7) (7.5-3)(7.5-5)}$

$\therefore A(\triangle ABC) =\sqrt{7.5(0.5) (4.5)(2.5)}$

$\therefore A(\triangle ABC) =\sqrt{42.1875}$

$\therefore A(\triangle ABC) =6.49519053$

$\therefore A(\triangle ABC) =6.495\: ft^2$
