Question

find the area of following triangles having sides given.(heron's formula). a=3cm b=4cm c=5cm​

Answer 1

Answer:

side = 3cm,4cm, 5cm

s= 5+4+3/2

s= 6

so

ATP,

√S(S-A)(S-B)(S-C)

√ 6*3*2*1

√ 36

6

Answer 2

Answer:

Step-by-step explanation:

given: sides a=3cm b=4cm c=5cm

first we need to find semi perimeter(s)

s=a+b+c/2 = 3+4+5/2 = 12/2 = 6

hence semi perimeter is 6

then using herons formula

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

we know

=$\sqrt{6(6-3)(6-4)(6-5)}$

=$\sqrt{6(3)(2)(1)}$

=$\sqrt{6(6)}$

=$\sqrt{36}$

=6

so the area of triangle abc is 6 $cm^{2}$
