Find the length of largest scale which can measure the boundary completely.
​

Answer 1

Answer:

The scale should be of 71.52m

Explanation : Here we have to find the perimeter of the rectangle = 2( L + B )

L = 20 (100) + 16

2000 + 16 = 2016 cm

B = 15 (100) + 60

1500 + 60 = 1560 cm

2 ( 2016 + 1560 )

2 ( 3576 ) = 7152 cm

In metre = 7152/100 = 71.52 m
