Question

please ans the picture.. ​

Answer 1

Answer:

a= 42 cm , b = 34 cm , c = 20 cm

Perimeter = a+b+c = (42+34+20) = 96 cm

Semiperimeter = 96/2 = 48 cm

Area of triangle = √s (s-a) (s-b) (s-c)

= √48 (48-42) (48-34) (48-20)

= √48 (6) (14) (28)

= √48 (2352)

= √112896

= √2.2.2.2.2.2.2.2.21.21

= 2.2.2.2.21

= 336 Sq. cm

Hope it helps....
