Solution:

ATQ

Length of a rectangular field is thrice it's breadth

Let length of rectangular field be = 3x

And

Breadth of rectangular field = x

Perimeter of rectangular field = 560m

Now as we know perimeter of rectangular field is equivalent to 2(Length + Breadth).

560 = 2(3x + x)

560 = 2(4x)

560 = 8x

x = 70m

3x = 3×70 = 210m

Breadth of rectangular field = x = 70m

Length of rectangular field = 3x = 210m

Hence, Length of rectangular field is 210m.

560 = 2(4x)

560 = 8x

x = 70m

3x = 3×70 = 210m

• Breadth of rectangular field = x = 70m

• Length of rectangular field = 3x = 210m

Hence, Length of rectangular field is 210m.
