Question

In abc c square =asquare +bsquare then 45(s-a) (s-b) (s-c) get the value

Answer 1

s=AplusBplusC divide by 2
it is a formula
A=40 B=30 C=20
s=a plus bplus c divide by 2
s = 40 plus 30 plus 20 divide by 2 is equql to 45
so; s = 45
s(s–a) (s–b)(s–c) this formula un under root
45(45-40)(45-30)(45-20)in under root
45multiply by 5 multiply by 15 multiply by 25 in under root
and its factor in undre root
factor of 45is 5 multiply by 9 factor of 5 is 5 factor of 15 is 3 multiply by 5 factor of 25 is 5multiply by 5 so pair of 5is 3 time and 9 and is in under root ok
ans is 125and 27 is on under root
