plz give a step by step solution so I can easily write the solution in my notebook
​

Answer 1

Answer:

384m

Step-by-step explanation:

LET THE COMMON RATIO BE x.

LENGTH = 7x

BREADTH = 5x

ACCORDING TO THE QUESTION,

7x = 112m

=> x = 16m

LENGTH = 112m

BREADTH = 16*5 = 80m

PERIMETER = 2*(112+80)

                    = 2*192

                     => 384m
