Question

the length of orange and green ribbons are 3m 15cm and 5m 25cm respectively. find the total length of both​

Answer 1

Answer :

The total length of the ribbon = 8.4 m

Step-by-step explanation :

Given,

• The length of orange ribbon = 3 m 15 cm
• The length of green ribbon = 5 m 25 cm

To find,

• the total length of the ribbon

Solution,

we know,

  1 m = 100 cm

 1 cm = 0.01 m

➟ The length of orange ribbon

           = 3 m 15 cm

           = 3 m + 15 cm

           = 3 m + (15 × 0.01) m

           = 3 m + 0.15 m

           = 3.15 m

➟ The length of green ribbon

          = 5 m 25 cm

          = 5 m + 25 cm

          = 5 m + (25 × 0.01) m

          = 5 m + 0.25 m

          = 5.25 m

⮕ The total length of the ribbon = length of orange ribbon + length of green ribbon

          = 3.15 m + 5.25 m

          = 8.4 m

Therefore, the total length of the ribbon = 8.4 m
