Question

6. The area of a triangle is given by Vs(s-a)(s -- b)(s -b). If a = 15 cm,
b = 8 cm, c = 17 cm and s 20 cm, find the area of the triangle.
​

Answer 1

Answer:

60

Step-by-step explanation:

By the heron formula

Area of the triangle =

$\sqrt{s (s - a)(s - b)(s - c)}$

$\sqrt{20(20 - 15)(20 - 8)(20 - 17)}$

$\sqrt{20 \times 5 \times 12 \times 3}$

$\sqrt{5 \times 4 \times 5 \times 4 \times 3 \times 3}$

$5 \times 4 \times 3$

$60$
