Two sides of triangle are 40 cm and 24 cm and its semi perimeter is 48 cm find the thrid side of a triangle

SOLUTION

AS WE KNOW ,

PERITMETER = SUM OF THE MEASURE OF THE ALL SIDES .

USING THIS CONCEPT, WE CAN FIND THE THRID SIDE TOO

TWO SIDES =40 CM AND 24 CM

SEMI PERIMETER =48 CM

PERIMETER =2( SEMI PERIMETER)=2(48)=96 CM

THEN THE THIRD SIDE=

PERIMETER- ( SUM OF 2 SIDES )

=96-(40+24)

=96-64

=32 CM

So it's true
