Let the length of the samller field = L width of the smaller field = W So the area of the smaller field = WL = K Now the length of the bigger field = 2L Width of the bigger field = 4W So the Area = 4W * 2L = 8WL = 8K Therefore, the area of the larger field is greater than the area of the smaller field = 8K - K = 7K ans: 7K
