Find the breadth of arectangular plot of land if its area is 3200 m² And the length is 80 m² Also find the perimeter of the plot . What will be the cost of the diggjng the land at Rs 25 per m²​

Sagot :

Answer:

  • 40 m wide
  • 240 m perimeter
  • ₹80,000 cost to dig

Step-by-step explanation:

Given a land area of 3200 m² with a length of 80 m, you want the width, perimeter, and cost of digging at ₹25/m².

Width

The formula for the area of a rectangle can be used to find the width of the plot.

  A = LW . . . . . . area is the product of length and width

  3200 m² = (80 m)W . . . . . fill in given values

  40 m = W . . . . . . . . . . . . divide by the coefficient of W

The width of the plot is 40 m.

Perimeter

The perimeter can be found using the formula ...

  P = 2(L +W)

Using the length and width we know, this is ...

  P = 2(80 m +40 m) = 2(120 m)

  P = 240 m

The perimeter of the plot is 240 m.

Digging cost

The cost of digging will be the product of the number of square meters and the cost of digging each one:

  digging cost = (3200 m²)×(₹25 /m²) = ₹80,000

The cost of digging the land is ₹80,000.
