Question

Find the area of a triangle which dimensions is 10 meters, 11 meters, 12 meters ​

Answer 1

Given :

⬤ Sides of Triangle are 10 m , 11 m and 12 m .

To Find :

⬤ Area of Triangle.

Solution :

Let :

• Side a = 10 m .
• Side b = 11 m .
• Side c = 12 m .

Semi Perimeter = a + b + c/2

Side Perimeter = 10 + 11 + 12/2

Semi Perimeter = 33/2

Semi Perimeter = 16.5

Now :

Area = √s (s-a) (s-b) (s-c)

Area = √16.5 (16.5-10) (16.5-11) (16.5-12)

Area = √16.5 × 6.5 × 5.5 × 4.5

Area = 2654.4375 $.$

Therefore , The Area of Triangle is 2654.4375 .

Answer 2

Given :

⬤ Sides of Triangle are 10 m , 11 m and 12 m .

To Find :

⬤ Area of Triangle.

Solution :

Let :

Side a = 10 m .

Side b = 11 m .

Side c = 12 m .

Semi Perimeter = a + b + c/2

Side Perimeter = 10 + 11 + 12/2

Semi Perimeter = 33/2

Semi Perimeter = 16.5

Now :

Area = √s (s-a) (s-b) (s-c)

Area = √16.5 (16.5-10) (16.5-11) (16.5-12)

Area = √16.5 × 6.5 × 5.5 × 4.5

Area = 2654.4375 ..

Therefore , The Area of Triangle is 2654.4375 .
