Question

1.) The cost of ploughing a square farm is the same as ploughing another farm that is rectangular in shape. The rate of ploughing is the same in both the cases. The side of the square farm is 20 m and the length of the rectangular farm is 40 m. Find the breadth of the farm.
​

Answer 1

Answer:

5 is the breadth

Step-by-step explanation:

first we will take

15+15 =30 is length and

40 - 30 = 10

10÷2=5 is breadth

Answer 2

Answer:

Area of the square farm = 20×20m2.

Area of the square farm = 400m2 ---(1).

We know that the area of the rectangle length l and breadth b units is l×b sq units.

Area of the rectangular farm = 40×bm2 ---(2).

From equations (1) and (2), we have

⇒40×b=400.

⇒b=40040.

⇒b=10m.

We have found the breadth of the rectangular farm as 10 m.
