Question

The perimeter of the triangular plot is 16m. If the measures of its two
sides are 5m and 6m. then find the area of the triangle using heron's formula . (answer the question to become as brainalist and I don't want the third side I want the area for this question ) pls fast pls

Answer 1

Answer:

12m² , using herons formula.... here s =perimeter/2

Answer 2

Answer:

the area is 12 sq.cm

Step-by-step explanation:

perimeter (p) = 16 cm

third side= 16-5+6

              = 5 cm

a=5,b=6,c=5

semi perimeter (s)=p/2 = 16/2 =8

area using Herons Formula:

         =$\sqrt{s(s-a)(s-b)(s-c)}$

         =$\sqrt{8*3*2*3}$

         =$\sqrt{144}$

         = 12 cm²
