Question

the side of a triangle are 16 cm , 30 cm, 34 cm . It's area in ( in cm ² ).1​

Answer 1

Answer:

16+30+34 =80

Step-by-step explanation:

after getting the answer 80 divide it by 2 and the answer will be 40

√40(40-16) (40-30)(40-34)

√40×24×10×6

√57600

then do prime factorisation after getting it multiply it and u will get the answer

hope this helps you

Answer 2

Step-by-step explanation:

Question:-

The sides of a triangle is 16cm,30cm and 34cm. Find the area of the triangle in cm².

Answer:-

Given :-

Sides of a triangle = 16 cm,30cm and 34cm.

To find :-

Area of the triangle

Process :-

Firstly,we have to find the perimeter to find the area of the triangle.

Thus,the formula for perimeter is:-

$=s = \frac{a+b+c}{2} \\ \\ = s = \frac{16+30+34}{2} \\ \\ =s= \frac{80}{2} = 40cm$

Therefore,we can find the area using heron's formula.

The formula is:-

$=Area= \sqrt{s(s-a)(s-b)(s-c)} \\ \\ =Area = \sqrt{40(40-16)(40-30)(40 - 34)} \\ \\ = Area = \sqrt{40 \times 24 \times 10 \times 4} \\ \\ =Area = \sqrt{57600} = 240 {cm}^{2}$

Thus,the area of the triangle is 240cm².
