Q3) Perimeter of triangle-Sum of two sides= Third side

(20-13.2)cm= Third side

Third Side= 6.8cm

Q4) Each side= Perimeter of equilateral triangle÷3

Each side= (18.3÷3)cm

Answer:

3). the lenght of the third side if the triangle is 6.8 cm

4). each side of a equilateral triangle is 6.1 cm

process

3) the perimeter of the triangle =20 cm

the length of 1st side = 4.2cm

the length of 2nd side = 9cm

so, if we add the both sides we will get 13.2 . so we have to subtract the sum of the 2 sides with perimeter of triangle

13.2 - 20 = 6.8 cm

hence, the third side of the triangle = 6.8cm

process of 4 question

4) the perimeter of the equilateral triangle = 18.3 . so , we have to divide 18.3 by 6

answer = 6.1
