=. Find the cost of fencing a rectangular field 62 m long and 33 m wide at * 16 per metre.
- The length and the breadth of a rectangular field are in the ratio 5 : 3. If its perimeter is
128 m
find the dimensions of the field.
to the width of the fiel​

Answer 1

Let the length be 5x

the breadth be 3x

perimeter 128

2(5x+3x)=128

2(8x)=128

8x=128/2

8x=64

x=64/8

=8

5x8

3x8
