Question

an elastic band which is 72 cm long is streched to 90 cm. Find the percentage increase in its length​

Answer 1

Answer:

25% Increase

Step-by-step explanation:

Original Length= 72 cm

When stretched= 90 cm

Increase in length= 90-72= 18 cm

Percentage Increase= (Increase In Length/Original Length)×100

                                  = (18/72)×100

                                  = 25%
