Answer 1

Answer:

the sides of triangle is 12 metre and the 15 divided by 16 its semi perimeter is 16 find we can find the area of triangle using heron's formula

Answer 2

Given :

⬤ Sides of Triangle are 11 m , 15 m and 6 m.

⬤ Semi Perimeter of Triangle is 16 m .

To Find :

⬤ Area of Triangle.

Solution :

• Side a = 11 m
• Side b = 15 m
• Side c = 6 m

s = a + b + c/2

s = 11 + 15 + 6/2

s = 32/2

s = 16

Therefore , Semi Perimeter of Triangle is 16 m .

Now :

$\sf{Area = \sqrt{s(s-a)\:(s-b)\:(s-c)}}$

√16 (16 - 11) (16 - 15) (16 - 6)

√16 × 5 × 1 × 10

√4 × 4 × 5 × 5 × 2

4 × 5 √2

20 √2

Therefore , Area of Triangle is 20√2 m² .
