$\huge\color{pink}\boxed{\colorbox{Black}{❥Answer}}$

=> let the breadth if rectangular field be x meters.

☆ Given that:

The length of a rectangular field is thrice its breadth

=> length = 3×breadth

=> length = 3x

☆ perimeter:

=> perimeter = 2(L+B)

=> 40=2(3x+x)

=> 40=2(4x)

=> 40=8x

=> x 40/8

=> x=5

Breadth of rectangular field, x = 5m

Length of rectangular field,3x=3(5)=15m

Therefore, Dimensions of the field are 5 meters and 15 meters respectively

☆ Area of field:

=> Area = L×B

=> Area = 15m×5m

=> Area = 75m2

=> The Area of the rectangular is 75m2.
