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
