Question

The length of retcangular plot is 40 meters more than its breadth if the cost of fencing the plot at 53 per meter is Rs 10600 what is the length of the plot in meters

Answer 1

Answer:

Let the breath be x.

Let the length be x + 40

Perimeter = 2( x + x + 40)

= 2x + 2x +80

= 4x + 80

53(4x + 80) = 10600

212x + 4240 = 10600

212x = 10600 - 4240

212x = 6360

x = 6360

212

x = 30

So, the breadth = 30

So, the length = 30 + 40

= 70
