Answer:

Perimeter of triangle=sum of all sides

let the third side be x

24+7+x=56

31+x=56

x=56-31

=25

semi perimeter=a+b+c/2

=25+24+7/2

=28

by using heron's formula

area=√s(s-a)(s-b)(s-c)

=√28(28-25)(28-24)(28-7)

=√28multiplied by 3 multiplied by 4 multiplied by 21

=√7056

=84cm2

Step-by-step explanation:

I didn't get multiplication sign so I have written multiplied by so instead of multiplied by please make multiplication sign in heron's formula
