Answer:
Length = 178 yards and Breadth = 46 yards
Explanation:
The perimeter of the rectangular field is 448 yards
Let the width is b and the length of the field is (4b-6) yards
We need to find the dimensions of the playing field. We know that the perimeter of a rectangle is given by :
P = 2(l+b)
ATQ,
[2((4b-6)+b)] = 448
2(5b-6) = 448
5b-6 = 224
5b = 230
b = 46 yards
Length = (4b-6)
= 4(46) - 6
= 178 yards
Hence, the length and breadth of the field is 178 yards and 46 yards respectively.
