Question :
The lengths of two sides of triangle are 15cm and 12cm .The perimeter of triangle is 44 cm. The length of the third side of triangle is
Answer :
Explanation :
Perimeter = sum of all sides
Answer:
given,
Length of two sides of the triangle : -
let, 15cm be 'a'
12cm be 'b'
third side be 'c'
Perimeter of the triangle = 44cm.
to find :-
Length of the third side.
formula used : -
perimeter of the triangle = sum of its all sides
= a + b + c.
44cm = 15cm + 12cm + c
44cm = 27cm + c
c = 44cm - 27cm
= 17cm
length of the third side = c = 17cm.
