Question

If each side of triangle is haved then it’s perimeter will be dicreaued by

Answer 1

Step-by-step explanation:

let the length of sides of triangle are a,b,c

then

perimeter, P(original)=(a+b+c)

now the sides are halved

i.e. a/2, b/2,c/2

then

perimeter, P(new)= (a/2 + b/2 + c/2)= (a+b+c)/2

New perimeter is less than original perimeter

Change in perimeter =

P(original) - P(new)=(a+b+c)- (a+b+c)/2=

(a+b+c)/2
