Question

Mukesh put a ribbon border around the edges of a 15cm by 8cm picture to

create a frame. What is the total length of ribbon Mukesh uses?​

Answer 1

Answer:

just you need to take out the perimeter o the frame

by formula 2(l+b)

now , see

that 2(15+8)

= therefor 31 cm is perimeter

so the total of ribbon mukesh uses is also 31 cm

Answer 2

We need to find the perimeter for finding the length of the ribbon

Perimeter = 2( l + b )

Length of ribbon = 2( 15 + 8 )

= 30 + 16

= 46 cm

The total length of ribbon used by Mukesh = 46 cm
