Question

Q12. A picture frame is 20cm long and 15cm wide. The ratio of its length to its
perimeter in lowest term is *​

Answer 1

Answer:

the ratio is 4.3

Step-by-step explanation:

Width\breadth of picture = 20 cm

Length of picture =15 cm

Let P is the perimeter ,  l is length and b is breadth then  

p=2(l+b)

 =2(20+15)

 =70

Now ratio of length to its perimeter is given by

length/perimeter = 20/15 = 4/3
