Question

The length and breadth of a rectangular field are in the ratio 5:4. If its
perimeter is 108m, find the dimensions of the field.
Please Explain​

Answer 1

Answer:

Let the sides be = 5x,4x

Formula for Perimeter = 2(length +breadth)

= 108= 2(5x+4x)

= 108= 18x

= x= 6

So,sides are =

Length= 5x= 30 m

Breadth=4x= 24m

Answer 2

let be length=5x

let be breadth=4x

perimeter is 108m

perimeter of rectangle=2(l+b)

108m=2(5x+4x)

108m=2×9x

108m=18x

6m=x

length=5x

=5×6m

=30m

breadth= 4x

=4×6m

24m

I hope it help you
