Question

A field is 20 feet wide. If the cost of frequency at 10 rupees per metre is the 1500
how much the long off the field​

Answer 1

Answer:

Field is in the shape of Rectangle

and it is given that it's wide = 20 feet

and the cost of frequency at 10 rupees per meter is 1500

So to find the length

Area of field = 1500/10 = 150m²

And Area of rectangle = l × b =

and let length be l so ,

l × 20m = 150m²

l = 150m²/20m

l = 7.5 meter
