Question

The length and breath of rectangular field are in the ratio 11:7. If it's perimeter is 32m40cm ; find its dimensions.

Answer 1

Answer:

HI MATE!


1m = 100cm

32m = 3200cm

Perimeter = 32m 40cm => 3240cm.


Ratio of length and breadth = 11:7

Let the length and breadth be 11x and 7x respectively.


Perimeter = 2(length + breadth)

32m 40cm = 2( 11x + 7x )

3240 = 2(18x)

36x = 3240

x = 3240/36

x = 90


Length = 11x = 11*90 = 990cm = 9m 90cm
Breadth = 7x = 7*90 = 630cm = 6m 30cm
