Question

the triangle sides are 60
,100 and 140 find the area by herons formula​

Answer 1

Answer:

s = sum of sides of triangle / 2

= 60+140+100 /2 = 300/2 = 150

area of triangle = √ s × (S-A)× (s-b) × (s-c)

= √150 × (150-60 ) × (150-140 ) ×(150-100)

= √ 150 × 90 × 10 × 50

= √ 5×3×10 × 3×3×10×10×5×10

= 5×3 ×10×10 √3

= 1500√3
