Question

What is the semiperimeter of a scalene triangle of side k 2k and 3k​

Answer 1

Step-by-step explanation:

perimeter =k+2k+3k

=6k

Semiperimeter = 6k/2=3k

Answer 2

$\huge{\sf{\underline{Question:-}}}$

What is the semiperimeter of a scalene triangle of side k , 2k and 3k?

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\huge{\sf{\underline{Answer:-}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given:

▪︎A scalene triangle

▪︎Measure of first side = k units

▪︎Measure of second side = 2k units

▪︎Measure of first side = 3k units

⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:

▪︎Semiperimeter of Scalene triangle

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:

${\bf{Perimeter\ of\ triangle}}$

${\sf{= Sum\ of\ all\ sides}}$

${\sf{= 1st\ side + 2nd\ side + 3rd\ side}}$

${\sf{= k + 2k + 3k}}$

${\sf{= 6k\ units}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

${\bf{Semiperimeter\ of\ triangle}}$

${\sf{= Perimeter ÷ 2}}$

${\sf{= 6k ÷ 2}}$

${\sf{= 3k\ units.}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\boxed{\sf{\therefore Semiperimeter\ of\ triangle\ is\ 3k.}}$
