Answer 2

Answer:

Here's your answer

Step-by-step explanation:

Given :- Perimeter of a Triangle = 44cm

It's sides = 9:7:6

Let the sides be 9x , 7x and 6x.

Therefore, Perimeter = a + b + c

9x + 7x + 6x = 44cm

22x = 44 cm

x = 44

-----

22

x = 2

Therefore , 9x = 9 × 2 = 18cm

7x = 7 × 2 = 14cm

and , 6x = 6 × 2 = 12 cm

Now ,

Let's find area of the given triangle.

S = a+b+c

----------

2

S = 18+14+12

-------------

2

S = 44

----

S = 22cm

Area of Triangle,

By Heron's Formula,

(Make Pairs of same digits )

(Make Pairs of same digits )

2 \times 2 \times 2 \sqrt{11 \times 2 \times 5}

8 \sqrt{110}

8 \times 10.488

= 83.904cm^2
