Question

The semi perimeter of a triangle is half of the perimeter. For the triangle below the semi-perimeter is (a+b+c)/2. What is the ratio of the side of an equilateral triangle to its semi-perimeter?

a) 01:02
b) 01:03
c) 02:03
d) 01:06​

Answer 1

hundred times digit is added to 10 times the digit which is the added to 1 digit give 3 digit number if X Y and Z are the one tenth and hundreds digit respectively then Express the number using an algebraic expression

Answer 2

Answer:

(d)

if 'a' is side of equilateral triangle then 3a is perimeter and 3a/2 is semi-perimeter . Now ratio a/(3a/2)=2/3
