Question

if the sides of a triangle are 40 cms,24 cms and 32 cms then it's semi-perimeter is 48 it is true or false​

Answer 1

Given: sides of a triangle are 40 cms,24 cms and 32 cms

it's semi-perimeter is 48

To Find : true or false​

Solution:

Semi perimeter of Triangle = (a + b + c)/2

where a , b & c are three sides of a triangle

a = 40

b = 24

c = 32

s = (40 + 24 + 32)/2

=> s = 96/2

=> s = 48 cm

TRUE

Yes its true that semi perimeter of triangle is 48 cm

if the sides of a triangle are 40 cms,24 cms and 32 cms then it's semi-perimeter is 48 - TRUE

Answer 2

SOLUTION

TO CHECK

If the sides of a triangle are 40 cm ,24 cm and 32 cm then it's semi-perimeter is 48 cm it is true or false

CONCEPT TO BE IMPLEMENTED

For a triangle

1. Perimeter = Sum of the three sides of the triangle

2. Semi perimeter is defined as half of the perimeter

EVALUATION

Here it is given that the sides of a triangle are 40 cm ,24 cm and 32 cm

∴ Perimeter

= ( 40 + 24 + 32 ) cm

= 96 cm

∴ Semi perimeter

$\displaystyle \sf{ = \frac{96}{2} \: \: cm }$

$\displaystyle \sf{ = 48 \: \: cm }$

Hence the statement is TRUE
