Answer 1

Step-by-step explanation:

length 12cm

Answer 2

Answer:  12cm or 65$\frac{1}{3}$cm

Step-by-step explanation:

If length: breadth = 3:7

then this is the solving

let us assume the length to be x

3:7 = x:28

3  :  7

x  :  28  cross multiply

7x = 28 × 3

x = 28 × 3/7

= 4 × 3 = 12

and the length would be 12cm

but if  breadth : length = 3:7 (with the length being the longer side)

then this is the solving

let us assume the length to be x still,

3:7 = 28:x

3  :  7

28: x  cross multiply

3x = 28 × 7

x = 28 × 7/3

= 196/3 = 65$\frac{1}{3}$

and the length would be 65$\frac{1}{3}$cm

Most times the length is the longer side so you should probably pick the second explanation
