If x is the number of chairs in a row
4x + 5 = 2x + 17
2x = 12
x=6
There are 6 chairs in each row. Now you have to find the total
4x+5 = 4(6)+5 = 29
And now double check
2(x) + 17 = 2(6)+17 = 29

Or 0.0714 (3sf)
From the text you can derive the following equations:
(1) A = bh/2 = 8
(2) and h = b+6
Fill in h in (1):
b(b+6)/2 = 8 => b^2 + 6b = 16 with the quadratic formula or simply trying some values for b you can find b=2, so h=8.
