Question

3. The length of a rentagular feild is 200m and width is 100m find the cost of ploughing the flied at the rate of Rs 10 per metre square.
​

Answer 1

Answer:

₹ 200,000

Step-by-step explanation:

Given-

Length of the field = 200 m

Width of the field = 100 m

Cost of plowing per metre square = Rs 10

Solution) area of the field = l × b

                                          = 200 × 100

                                          = 20,000 m²

Total cost of plowing the field = 20,000 × 10

                                                   = 200,000

∴ cost of plowing the field will be ₹ 200,000.

Answer 2

Answer:

$\red\bigstar$ Cost of ploughing the field = ₹ 200000.

SOLUTION

Length of the rectangular field = 200m.

Breadth of the rectangular field = 100m.

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(5,0){2}{\line(0,1){3}}\multiput(0,0)(0,3){2}{\line(1,0){5}}\put(0.03,0.02){\framebox(0.25,0.25)}\put(0.03,2.75){\framebox(0.25,0.25)}\put(4.74,2.75){\framebox(0.25,0.25)}\put(4.74,0.02){\framebox(0.25,0.25)}\multiput(2.1,-0.7)(0,4.2){2}{\sf\large 200m}\multiput(-1.4,1.4)(6.8,0){2}{\sf\large 100m}\put(-0.5,-0.4){\bf }\put(-0.5,3.2){\bf }\put(5.3,-0.4){\bf }\put(5.3,3.2){\bf }\end{picture}$

As we know that ploughing is done inside the perimeter of the field , we must find the area of the rectangle.

Area of a rectangle =  l × b , Where l is the length and b is the breadth of the rectangle.

Here,

l = 200m.

b = 100m.

⇒ Area of the  rectangular field = 200 × 100

⇒ Area of the  rectangular field = 20000m².

Cost of ploughing the field = Rate of ploughing the field × Area of the field

Here,

Rate of ploughing the field = ₹10/m².

Area of the field = 20000m².

∴ Cost of ploughing the field = 20000 × 10

⇒ Cost of ploughing the field = ₹ 200000.
