Answer 2

Answer:

2

Step-by-step explanation:

x be width of flower bed

cost of flower bed =x^2 * 4

area of gravel =total area - area of flower bed

=10^2 - x^2

cost of gravel = (10^2 -x^2) * 3

total cost =(10^2-x^2) * 3 + x^2 * 3 =364

= > x^2 + 300 = 364

=> x^2 =64

x=8

width of gravel = 10 -x =10-8 =2
