Question

Find the area of a triangle park whose sides are 15cm , 11cm, 6cm

Answer 1

Answer:

Use the Heron's formula. At first take out semiperimeter which will be (15+11+6)/2=16

Now we know Heron's formula which is

area of a triangle

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

Where a, b, c are the sides of the triangle. Hope it helps you. Please help me by marking the answer the brainliest

Answer 2

Answer:

Sides of triangle = 15cm, 11cm, 6cm

Perimeter of triangle (15+11+6)cm

2s = 32cm

s= 16cm

By Heron's Formula,

Area of triangle = √s(s-a) (s-b) (s-c)

=[√16 (16-15) (16-11) (16-6) ] m²

= ( √16*1*5*10) m²

= 20√2 m²

Therefore, Area of triangle is 20√2 m².
