area of square field =44*44 = 1936
area of square bed = (44-2x)^2
area of gravel = 1936 - (44 -2x)^2 = 176x - 4x^2
cost of gravelling = (176 - 4x^2) * 1.50 = 6(44x - x^2)
cost of laying flower bed = (44-2x)^2 * 2.75 = 11(22 - x)^2
according to the question = 11(22-x)^2 + 6(44 - x^2) = 4904
on solving the above equation you will get x = 2 or x = 42
but x cannot be equal to 42 (because 44 - 2x will be negative)
so, x =2 (width)
hope it helps. pls mark as brainliest
