Question

Length and breadth of a rectangular field are 70 m and 35 m respectively. Find the ratio of the length to the breadth of the field
(A) 5:10
(B) 10:2
(C) 2:1
(D) 10 : 5​

Answer 1

Answer:

Solution

Let the length of the field be 9x and breadth be 5x.

9x×5x=14580

45x

2

=14580

x

2

=324

x=18

Hence, length=162m and breadth=90m.

Perimeter = 2(l+b)=2(162+90)=2(252)=504m

Therefore,

Cost of fencing = 504×3.25=1638 Rs.

Step-by-step explanation:

Answer 2

$\sf Length = 70 m \:\:\:\: Breadth = 35m\\\\ \sf Ratio = \frac{70}{35}\\\\ \sf Ratio\: of\: their\: length\: and\: breadth = 2:1$
