Question

the length and breadth of a rectengular field are in 5:3 . If the perimeter is 64 m. find the dimensions. The cost of fencing a rectangular field is at rs 14.60per m is 1606 .If the width of a field is 23 m. Find its length

Answer 1

Answer:

Step-by-step explanation:

Let length of rectangular field is 5x and breadth 3x

Perimeter=64m

Perimeter=2*l+b

2*5x+3x=64

2*8x=64

x=4

Length=4*5=20

=4*3=12

Next question

Perimeter of field=1606/14.60=110m

Perimeter=2*l+b

2*l+23=110

2l+2*23=110

2l+46=110

2l=110-46

2l=64

l=64/2=32

If you want to check your answer you can put the value of l(length) in formula of perimeter and see your answer would be 110
