Question

The length and breadth of a rectangular field is 5:3 . If the area is one hextare and 3500 sq mts. Then find the perimeter

Answer 1

Let the

length=5x

breadth=3x

Area of rectangle=l*b

1 hectare=1000 meter square

area=1000+3500=4500

4500=5x*3x

15x^2=4500

x^2=4500/15

x^2=300

x=17.32

5x=17.32*5=86.6 meter

3x=17.32*3=51.96 meter
