Question

are lot of length 50 M and breadth 35 within is to be surrounded externally by a path which is 2 metre wide find the cost of levelling the path @ rupees 30 per metre square​

Answer 1

Step-by-step explanation:

Length=50m

Breadth=35m

Width of path=2m

Area of path =(2×50×2)+(2×35×2)

=200+140

=340m²

I hope it will help you and other people,as it is the shortest answer to solve this question.

Answer 2

Question:-

A rectangular lawn of length 50 m and breadth 35 m is to be surrounded externally by a path which is 2 m wide. Find the cost of levelling the path at the rate of Rs 30 per m².

solution:-

Let, L be the length of rectangle and B be the breadth rectangle.

By Question:-

We know formula of

=> Area of rectangle = L × B

=> Area of rectangle = 50 × 35

=> Area of rectangle = 1750 m²

=> X = 1750 m²

we know that length and breadth increase by 2 m from their both ends.

so,

=> L = 50 + 2 + 2 = 54 m.

=> B = 35 + 2 + 2 = 39 m.

We know formula of

=> Area of rectangle + path = L × B

=> Area of rectangle + path

= 54 × 39

=> Area of rectangle + path

= 2106 m²

=> Z = 2106 m²

=> Area of path =( Z ) - ( X )

=> Area of path = 2106 - 1750

=> Area of path = 356 m²

Area of path 356 m².

To finding cost of surfing the path

=>Area ×Rs 30 = 360 × 30

= Rs 10680

Hence cost of levelling the path

is Rs 10680
