Question

An quadrilateral triangle has sides of length 20CM if the side of triangle is increased by 40 % then find what fraction of the perimeter of the new triangle is perimeter of previous triangle​

Answer 1

Step-by-step explanation:

Given :

• Side of eq A = 20cm Perimeter = 3 × 20 = 60cm Length of new side after increasing 40%

• => 20 x 140/100 = 28cm

• Perimeter = 3 × 28 = 84c

• So,

• Required fraction = new

• perimeter/old perimeter => 84/60 = 21/15 Ans
