Answer 2

As we know that area of rectangle (A) is given as

A = l × b

Let the length of the rectangular plot be x meter.

Given:-

Area of rectangular plot = 340m²

Breadth of rectangular plot = 17m

∴ x × 17 = 340

$\sf \implies\dfrac{340}{17} = 20m$

Hence the lenth of rectangular plot is 20m.

As the perimeter of the rectangle is given as-

p=2(l+b)

∴p = 2(17+20)

⇒p = 2×37

⇒p = 74m

Cost of fencing given =Rs.5.70 per metre

Therefore,

Cost of fencing for 

⇒74m=5.7×74

⇒Rs.421.8

Hence the cost of surrounding the plot with a fence is Rs.421.8.
