Question

In  ABC, if  B = 90˚, AB = 8 cm and BC = 15 cm, then the semi perimeter s of the triangle = 20 cm.​

Answer 1

Step-by-step explanation:

To find this answer we need to apply the below formula

$THEOREM. K = sqrt[ s(s - a)(s - b)(s - c) ], where s = ½(a + b + c) is the triangle's semi-perimeter.$
