So hmmm check the picture below
now

now, that's how many yard³ are there for that slab, now, how much is the cost?
well, each yd³ costs $40, thus
3x - 2 = x + 1
2x = 3
x = 3/2
x = 1.5
3x - 2 = 3(1.5) - 2 = 2.5
or
x + 1 = 1.5 + 1 = 2.5
P = 4(2.5) = 10
perimeter of square is 10 cm so side of square = 2.5cm
