Answer 1

Given :-

The sides of an triangle are 7 cm, 24 cm and 25 cm.

To Find :-

To Find :-The semi perimeter of the triangle.

Analysis :-

Firstly, we've to find the perimeter of the triangle by substituting the values given in the formula of perimeter of triangle.

• In order to get the semi perimeter, divide the perimeter we got by two.

Solution :-

• By the formula,

$\underline{\boxed{\sf Perimeter \ of \ triangle=a+b+c}}$

✯Given that,✯

• a = 7 cm

• a = 7 cmb = 24 cm

• a = 7 cmb = 24 cmc = 25 cm

⇝ Substituting their values,

⇝ Perimeter = 7 + 24 + 25

⇝ Perimeter = 56 cm

⇝ Therefore, the perimeter is 56 cm.

• Finding semi perimeter,

$\underline{\boxed{\sf Semi \ perimeter=\dfrac{Perimeter}{2} }}$

⇝Given that,

⇝ Perimeter = 56 cm

⇝ Substituting them,

⇝ Semi perimeter = 56/2 = 28 cm

☆$\sf Therefore\:the\: semi \:perimeter\: is \:28 cm.$☆
