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

1 and 4 = 120

2 and 3 are diagonal so they both = 60

Same thing for the bottom

1=120

2=60

3=60

4=120

5=120

6=60
