Question

find the area of the triangle whose sides are 60, 100, 140 using herons formula


Pls answer this question ​

Answer 1

Answer:

Area = 2598.08

A side = 60

B side = 100

C side = 140

I hope it's helpful to you. give me thanks and follow me plz

Answer 2

Here, a = 60 m

b = 100 m

c = 140 m

Step 1: Find s

s = (a+b+c)/2

s = (60+100+140)/2

s = 300/2 m

s= 150m

s – a = (150 – 60) m = 90 m,

s – b = (150 – 100) m = 50 m,

s – c = (150 – 140) m = 10 m.

step2: find area

Therefore, area of the park ABC = √ s(s-a)(s-b)(s-c) = √ 150 x 90 x 50 x 10

√2×5×3×5×2×3×3×5×2×5×5×2×5

√2×2×2×2×3×3×3×5×5×5×5×5×5

=2×2×3×5×5×5√3
