Question

Find the area of a triangle whose sides are 30,50, 60cm.

Answer 1

area of a triangle = a+b+c/2
where a ..30cm
b....50cm
c...60cm
so a+b+c/2

30+50+60/2
140/2
70 cm is the answer i hope it will help you

Answer 2

Hey !!!

By using herons formula , we can find the area if triangle .

So,

let us see !!!

S = 1/2 ( a + b +c)

s = 1/2 ( 30+50+60)

s = 1/2(140)

s = 70.

Now, by using Pythagoras theorem . formula is

∆ = √s(s-a)(s-b)(s-c)

∆ = √70(70-30)(70-50)(70-60)

∆ = √70×40×20×10

∆= √2×7×5×2×2×5×2×2×2×5×5×2

∆ = 2×2×2×5×5√7×2

∆ = 200√14 cm² Answer

Hope it helps you !!!
