Question

find the area of a triangle whose sides qre 50 cm, 30 cm, 40 cm​

Answer 1

Answer:

area of triangle is 120cm

Answer 2

Answer:

Area = 10√60 cm²

Step-by-step explanation:

given -

sides of triangle = 50 cm, 40 cm, 30 cm

to find -

area of the triangle

solution -

We will use the formula of heron = √(s-a)(s-b)(s-c)

s (semi perimeter) = (a+b+c)/2

= (50+40+30)/2

= 120/2

= 60 cm

area = √(s-a)(s-b)(s-c)

= √(60-50)(60-40)(60-30)

= √10×20×30

= √10×10×2×10×3

= √10×10×10×2×3

= √10²×10×2×3

= 10√60 cm²

Hence the area of the triangle = 10√60 cm².
