Question

find the area of triangle two sides of which are 13m and 12m and the perimeter is 30m​

Answer 1

Answer:

300m

Step-by-step explanation:

side 3=perimeter- side1=side2

side 3=30m- 12m=13m

side 3=5m

semiperimeter=perimeter/2

                        =30/2

                        =15m

area=$\sqrt{s(s-a)(s-b)(s-c)$

      = $\sqrt{15* 15-12 *15-13 * 15-5}$

     =$\sqrt{15*2*3*10} \\\sqrt{900}$

     =30m
