Answer:
y=-3x+15
Step-by-step explanation:
Half the area is 6000.
let x be the width of the walk so the inner rectangle has a length of 150-2x and width 80-2x and hence its area is (150-2x)(80-2x) which is equal to 6000.
so now we have an equation in terms of x which reduces to a quadratic and we solve for x
